The FCC Wants You To Know  
This scanner has been tested and found to comply with the limits for a scanning receiver,  
pursuant to Part 15 of FCC rules. These limits are designed to provide reasonable protection  
against harmful interference in a residential installation. This scanner generates, uses, and  
can radiate radio frequency energy and, if not installed and used in accordance with the  
instructions, may cause harmful interference to radio communications.  
However, there is no guarantee that interference will not occur in a particular installation. If  
this scanner does cause harmful interference to radio or television reception, which can be  
determined by turning the scanner on and off, you are encouraged to try to correct the  
interference by one or more of the following measures:  
• Reorient or relocate the receiving antenna  
• Increase the separation between the scanner and the receiver  
This device complies with Part 15 of FCC rules. Operation is subject to the following two  
conditions: 1) This device may not cause harmful interference, and 2) this device must  
accept any interference received, including interference that may cause undesired operation.

Scanning Legally  
Your scanner covers frequencies used by many different groups, including police and fire  
departments, ambulance services, government agencies, private companies, amateur radio  
services, military operations, pager services, and wire line (telephone and telegraph) service  
providers. It is legal to listen to almost every transmission your scanner can receive.  
However, there are some transmissions that you should never intentionally listen to. These  
include:  
• Telephone conversations (cellular, cordless, or other private means of telephone signal  
transmission)  
• Pager transmissions  
• Any scrambled or encrypted transmissions  
According to the Electronic Communications Privacy Act (ECPA), you are subject to fines  
and possible imprisonment for intentionally listening to, using, or divulging the contents of  
such a conversation unless you have the consent of a party to the conversation (unless such  
activity is otherwise illegal).  
This scanner has been designed to prevent the reception of cellular telephone transmissions  
and the decoding of scrambled transmissions. This is done to comply with the legal  
requirement that scanners be manufactured so they are not easy to modify to pick up these  
transmissions. Do not open your scanner’s case to make any modifications that could allow  
it to pick up transmissions that are illegal to monitor. Modifying or tampering with your  
scanner’s internal components or using it in a way other than as described in this manual  
could invalidate your warranty and void your FCC authorization to operate it.  
In some areas, mobile use of this scanner is unlawful or requires a permit. Check the laws in  
your area. It is also illegal in many areas (and a bad idea everywhere) to interfere with the  
duties of public safety officials by traveling to the scene of an incident without authorization.

In addition, here are a few more of the many features your scanner has. To get the most  
from your scanner, be sure to review this entire manual.  
APCO Project 25 Phase 1 Compatible – works on the latest 9600 bps systems, including  
systems that use C4FM and CQPSK modulation.*  
Four-line, 16-character, Alpha Display – makes it easy for you to see who is talking by  
displaying the assigned text tag instead of just a frequency or talkgroup ID number.  
Automatic Digital Detect – allows the scanner to switch to digital voice decoding when it  
detects valid APCO 25 data without any special programming.  
1000 Channels – lets you store frequencies in 10 banks of 100 channels each.  
1000 Talkgroup ID’s – lets you store 10 groups of 10 ID’s each per bank.  
Multi-System Tracking – scans conventional and trunking systems at the same time.  
Included PC Programming Software and Cable – makes programming your scanner  
much easier. Full-featured software included (no registration needed).  
10 Priority Channels – switches to the channel you assign as priority if there is activity,  
so you won’t miss a thing.  
Priority Talkgroups – increases the priority of selected talkgroups so the scanner is more  
likely to switch to them if there is activity.  
Priority Plus Scanning – lets you scan only those channels you have selected as priority  
channels.  
CTCSS and DCS Squelch Modes – prevents interference from stations not using the  
mode you select; search mode displays the CTCSS or DCS tone being used by the  
received station.  
Preprogrammed Service Search – makes it easy to find interesting frequencies used by  
public safety, news media, TV broadcast, weather, amateur radio, FRS, GMRS, special  
low power, railroad, aircraft, marine, and racing services.  
Data Skip – automatically skips frequencies that have a constant-level transmission such  
as used on data channels for some systems, paging systems, and internally generated  
birdies.  
SAME Weather Alert with FIPS – lets you set your scanner to listen for a SAME event  
code from the local weather service; sounds an alert and displays the text description for  
any alert received. FIPS programming lets you restrict the alerts to one county.  
Turbo Search – searches for activity on frequencies at up to 300 steps per second (in the  
5 kHz step ranges).  
Scanner Clone Mode – lets you connect your scanner directly to another scanner to  
clone all channels and settings.  
*Note: Performance on digital systems can vary due to signal quality, multipath interference, and cellular  
interference. Unlike analog trunking, where you can hear the audio with some interference mixed in,  
interference in a digital system completely blocks the signal. If you do not get good digital reception, try  
adjusting your location or your antenna until reception improves.

Using this Manual  
To get the most from this manual, review the contents to become familiar with the basic  
functions available. If you are new to scanning or trunktracking, be sure to read the  
“Understanding Scanning” section for a quick background on the technology behind the  
hobby.  
The first thing you’ll need to do is plug the AC charger into the scanner. See “Setting Up  
Your Scanner” if you need any help doing this.  
Next, you’ll want to listen to see what you can hear with your scanner. Install the antenna,  
then press SRVC and use the scroll bar to select TV Broadcast. Assuming you are in an  
area with a strong enough TV broadcast, your scanner should soon stop on a station’s audio  
program. Listen to this, or try searching another service for something more interesting,  
while you review the rest of the manual.

Understanding Scanning  
This section provides you with the background on how scanning works. You don’t really  
need to know all of this to use your scanner, but some background knowledge will help you  
to get the most from your BC796D.  
Conventional Scanning  
Conventional scanning is a relatively simple concept. Each group of users in a conventional  
system is assigned a single frequency (for simplex systems) or two frequencies (for repeater  
systems) to use. Any time one of them transmits, their transmission always goes out on the  
same frequency. Up until the late 1980’s this was the primary way that radio systems  
operated. Even today, there are a lot of 2-way radio users who operate using a conventional  
system:  
• Aircraft  
• Amateur Radio  
• FRS/GMRS Users  
• Broadcast AM/FM/TV Stations  
• Many Business Radio users  
When you want to store a conventional system, all you need to know is the frequency they  
operate on.  
When you are scanning a conventional system, the scanner stops very briefly on each  
channel to see if there is activity. If there isn’t, the scanner quickly moves to the next  
channel. If there is, then the scanner pauses on the transmission until it is over.  
Simplex Operation  
Simplex systems use a single frequency for both transmit and receive. Most radios using this  
type of operation are limited to line-of-sight operation. This type of radio is frequently used at  
construction job sites, and with inexpensive consumer radios such as GMRS/FRS radios.  
The range is typically 1-5 miles, depending upon the terrain and many other factors.  
Repeater Operation  
Repeater systems use two frequencies: one transmits from the radio to a central repeater;  
the other transmits from the repeater to other radios in the system. With a repeater based  
system, the repeater is located on top of a tall building or on a radio tower that provides  
great visibility to the area of operation. When a user transmits (on an input frequency), the  
signal is picked up by the repeater and retransmitted (on an output frequency). The user’s  
radios always listen for activity on the output frequency and transmit on the input frequency.  
Since the repeater is located very high, there is a very large line of sight. Typical repeater  
systems provide coverage out to about a 25 mile radius from the repeater location.

Trunked Scanning  
While conventional scanning worked great while there were only a few groups wanting to  
use the frequencies, with the advent of smaller, lower-cost radios more and more agencies  
and businesses wanted to take advantage of the utility of 2-way radio. As a result, the bands  
that were used most became full, so new users were not able to take advantage of the  
technology as quickly as they wanted.  
Trunking solved this frequency shortage by allowing multiple groups to use the same set of  
frequencies in a very efficient way. While each type of trunking system operates a little  
differently (see the next few sections), they all work on the same basic premise: even in a  
system with a lot of users, only a few users are ever transmitting at any one time.  
Instead of being assigned a frequency, as with conventional systems, each group is  
assigned a Talkgroup ID. A central computer controls the frequency each group operates  
on...and this frequency selection is made each time a user transmits. So, while on a  
conventional system queries, replies, and follow-ups are all on a single frequency, they  
could each be on completely different frequencies on a trunked system. This semi-random  
frequency assignment made monitoring such a system impossible prior to Uniden’s invention  
of the Trunktracking scanner.  
Motorola Trunking  
While there are 4 different types of Motorola trunking systems, they all use the same basic  
trunking method. The system consists of one control channel plus one or more voice  
channels (typically 10, 20, or 30 total channels). When a user presses Push To Talk (PTT)  
to transmit, their radio first sends their talkgroup information to the control channel. The  
computer then assigns that talkgroup to a specific voice channel and transmits that data  
over the control channel. All radios in that talkgroup switch over to the assigned voice  
channel and the user can begin speaking. This all typically takes place in about a  
second...the person transmitting hears a beep from their radio when the channel is assigned  
and it is OK to start talking.  
The four systems in use are:  
Motorola Type I – the radios send the radio ID, the fleet and subfleet talkgroup ID to the  
control channel each time they transmit. To program a Type I system, you need to know  
the system’s fleet map. The most common fleet maps are included at the back of this  
manual. You can also find fleet map resources on the web.  
Motorola Type II – the radios only send the radio ID and radio channel code to the control  
channel. The central computer keeps a database of radio ID’s and which talkgroup is  
assigned to which channel code for each radio, so with this system the user’s radio sends  
only about 1/3 the data as a Type I system with each transmission. Type II systems do not  
use Fleet-subfleet talkgroups; instead they use a 5-digit ID for each talkgroup.  
Type IIi Hybrid — these systems support a mix of both Type I and Type II users. Like  
Type I systems, you must know the system’s fleetmap to ensure proper tracking.  
Motorola Astro Digital — for channel control purposes, this type of system operates just  
like a Type II system — although the control channel can be a 3600 bps data rate (for  
mixed analog/digital systems) or a 9600 bps (for digital-only systems). Pure digital sys-  
tems can be implemented under APCO 25 Phase 1 or Phase 2 standards. Your BC796D  
is able to decode all unencrypted digitized voice traffic on either mixed mode or digital-only  
APCO 25 Phase 1 systems.

One big difference you will notice with digital versus analog transmissions, is that with  
analog systems, you might be able to hear weak signals interspersed with hissing. As you  
move further away from the system, the interference gradually increases until you are  
unable to make out the transmission. With digital systems, the cutoff point is much more  
abrupt. You might have a small area where partial decoding occurs...in which case you will  
hear partial and garbled audio. However, once the scanner is unable to receive the data well  
enough to decode it, the audio stops entirely. For the best range, antenna selection and  
placement is critical. See “Connecting an Antenna” for more information.  
EDACS Trunking  
EDACS trunking works in much the same way as Motorola trunking with a couple of major  
differences. In an EDACS system, each frequency used by the system is assigned a Logical  
Channel Number (LCN) so that less data needs to be transmitted by the control channel.  
Also, talkgroups are assigned in an Agency-Fleet-Subfleet (AFS) hierarchy. Also, there is  
one variation of EDACS called SCAT that your BC796D can monitor.  
Logical Channel Numbers – each frequency used by the system is assigned an LCN.  
This information is programmed into each user radio. When a user presses PTT, their  
radio sends their AFS information to the control channel. The computer then assigns that  
talkgroup to a channel and sends the LCN so that all other radios in that talkgroup will  
switch to the correct channel. To program a EDACS system in your scanner, you will need  
to know both the frequencies used by the system and the LCN for each frequency so that  
you can program the frequencies in LCN order.  
Agency-Fleet-Subfleet – talkgroup ID’s for EDACS systems are assigned in a way that  
makes it easy to see at a glance the affiliation of the user. Each radio is assigned a 2-digit  
agency identifier from 00 – 15. For example, 01 might be used by the police, 02 by  
ambulance service, 03 by the fire department, and so on. Each agency is then subdivided  
up to 16 times to provide fleet identification, and then 8 more times to identify subfleets.  
For example, the complete AFS for the Police Department West District’s dispatch channel  
might be 01-062. 01 identifies the agency as the police department, 06 identifies the fleet  
as the West district, and 02 identifies the subfleet as the dispatch channel. While these  
assignments are somewhat arbitrary and vary from system to system, there are many  
resources on the web for finding the assignments for most systems.  
Because of the logical hierarchy of the AFS system, your BC796D lets you assign wildcard  
ID’s that let you, for example, use only one ID memory to identify all units in either an  
agency or a fleet.  
EDACS SCAT – EDACS SCAT (Single Channel Autonomous Trunking) systems operate  
on a single channel and alternate control data with analog voice traffic. While your  
BC796D cannot track ID’s in this system, it can eliminate the control data so that all you  
hear is the voice transmissions when you monitor this type of system.

LTR Trunking  
®
LTR (Logic Trunked Radio) systems are trunking systems used primarily by business or  
private communications service providers, such as taxicabs, delivery trucks, and repair  
services. These systems encode all control information as digital subaudible data that  
accompanies each transmission, so there is no separate control channel. Users on an LTR  
system are assigned to specific talkgroups, which are identified by the radio as six digit  
numbers. These numbers are in the form AHHUUU, where:  
A= Area code (0 or 1)  
H= Home repeater (01 through 20)  
U= User ID (000 through 254)  
When the scanner receives a transmission on a channel set to the LTR mode, it first  
decodes the LTR data included with the transmission. In the ID Search mode, the scanner  
stops on the transmission and displays the talkgroup ID on the display. In the ID Scan mode,  
the scanner only stops on the transmission if the LTR data matches a talkgroup ID that you  
have stored in the bank’s talkgroup ID list and have not locked out.  
LTR systems are frequently programmed so that each radio has a unique User ID.  
LTR systems also need to be programmed into your scanner in channel-order.  
Since many LTR systems use only odd-numbered channel slots, you would program these  
systems using only the corresponding odd-numbered channels in a bank (for example, you  
would program a system with channels at 1, 3, 5, and 9 into Trunk 2 channels 101, 103,  
105, and 109).  
Understanding Banks and Channels  
The memory in your scanner is organized into 10 banks of 100 channels each. Each bank  
can contain conventional channels as well as 1 trunking system. For each trunking system,  
each bank can also store 10 groups of 10 talkgroup ID’s (100 per bank).

Setting Up Your Scanner  
Connecting an Antenna  
You must install an antenna before you can operate the scanner. You have been provided a  
standard telescopic antenna that works well with this scanner, but you may want to  
purchases another type to increase the range. To connect the telescopic antenna, simply  
connect it to the BNC type ANT. connector on the rear of the scanner. You can purchase a  
variety of scanner antennas for both mobile and base station available at a local electronics  
store. Choose the one that best meets your needs.  
When deciding on a mobile or base station antenna and its location, consider these points.  
• The antenna should be as high as possible on a vehicle or a house.  
• The antenna and its cable should be as far as possible from sources of electrical noise  
(ignition systems, gauges, and so on).  
• The antenna should be vertical for the best performance.  
Mounting an Antenna  
Once you choose an antenna, follow the mounting instructions supplied with the antenna.  
Then route the antenna cable to the scanner.  
The antenna connector on your scanner makes it easy to use the scanner with a variety of  
antennas, such as an external mobile antenna or an outdoor base station antenna.  
Always use 50 ohm coaxial cable, such as RG-58 or RG-8, to connect an outdoor antenna.  
For lengths over 50 feet, use RG-8 low-loss dielectric coaxial cable If your antenna’s cable  
does not have a BNC connector, you will also need a BNC adapter (available at a local  
electronics store).  
Follow the Installation instructions supplied with the antenna, route the antenna cable to the  
scanner, then connect it to the ANT. jack.  
Warning: Use extreme caution when you install or remove an outdoor antenna. If the  
antenna starts to fall, let it go! It could contact overhead power lines. If the  
antenna touches a power line, contact with the antenna, mast, cable, or guy  
wires can cause electrocution and death. Call the power company to remove  
the antenna. DO NOT attempt to do it yourself.  
Optional Antenna  
If you have chosen an optional mobile antenna, connect the antenna plug into the ANT.  
connector on the rear of the scanner. (For more information on antenna installation, please  
refer to the instruction guide that came with your antenna.)  
 
14  
Typical Mounting Methods  
The BC796D can be conveniently mounted on a table, bulkhead, overhead, or any other  
desired location (refer to figure below for typical mounting methods).  
Caution: Make sure there are no hidden electrical wires or other items behind the desired  
location before proceeding. Check that free access for mounting and cabling  
is available.  
• Table top mount  
• Bulkhead mount  
• Overhead mount  
Mounting the Scanner in Your Vehicle  
Before you mount the scanner, make sure you have all the necessary materials. Then confirm  
that the scanner fits your vehicle’s mounting area. This unit requires a mounting area of 2-3/8  
inch high by 6-15/16 inch wide by 6-9/16 inch deep (61 x 176.5 x 167 mm).  
Caution: Be sure to avoid obstructions behind the mounting surface.  
Follow these steps to mount the scanner in your vehicle.  
1. Choose a mounting location, then use the supplied  
mounting bracket as a template to mark the positions for  
the mounting screw holes.  
2. In the marked positions, drill holes slightly smaller than  
the supplied screws.  
3. Attach the mounting bracket to the mounting location  
using the supplied screws and lock washers.  
4. Attach the scanner to the mounting bracket using the  
supplied mounting knobs.  
5. Connect the antenna’s cable to the ANT. connector on  
the back of the scanner.  
Note: If the antenna cable’s connector does not fit in the ANT.  
connector, you might also need a Motorola-to BNC  
antenna plug adapter (available at a local  
electronics store).  
 
15  
Applying Power for Vehicle Installation  
You can power your scanner using either the supplied DC power cord or your vehicle’s  
cigarette lighter socket using DC cigarette lighter power cord.  
Caution: You must use a power source that supplies 13.8 V DC and delivers at least  
700 mA. Your standard 12 V car battery should be sufficient. The cord  
connector’s center tip must be set to positive and its plug must fit the scanner’s  
DC 13.8 V jack. The supplied DC power cord meets these specifications. Using a  
power cord that does not meet these specifications could damage the scanner or  
the adapter.  
• Always connect the adapter or DC power cord to the scanner before you connect it to the  
power source. When you finish, disconnect the adapter or DC power cord from the power  
source before you disconnect it from the scanner.  
• For added safety and to protect your scanner,  
disconnect the cable from your vehicle battery’s  
negative (-) terminal before you begin.  
Follow these steps to connect the supplied DC power cord.  
1. Connect the power cord’s black wire to a chassis ground, such  
as a metal screw attached to a metal part of the vehicle’s frame. Be sure that the screw  
is not insulated from the frame by a plastic part.  
2. Connect the power cord’s red wire (with in-line fuse) to a source  
of voltage that turns on and off with the ignition switch, such as  
a spare accessory terminal in your vehicle’s fuse box.  
3. Insert the power cord’s barrel plug into the DC 13.8 V jack  
on the back of the scanner.  
4. Reconnect the cable to the vehicle battery’s negative (-)  
terminal.  
To power the scanner from a vehicle’s 12 V power source  
(such as a cigarette-lighter socket), you need a cigarette-lighter  
adapter.  
To connect an optional DC cigarette-lighter power cable, insert  
its barrel plug into the DC 13.8 V jack on the back of the scanner, then plug the power cable  
into your vehicle’s cigarette lighter socket.  
Note: If you use a cigarette-lighter power cable and your vehicle’s engine is running, you  
might hear electrical noise from the engine while scanning. This is normal.  
 
16  
Desktop Installation  
You can place this scanner on a desk, shelf, or table to use it as a base station.  
1. Flip up the feet for desk installation.  
2. Extend the antenna to full vertical position.  
Adjust the angle for best reception.  
Applying Power Using Standard AC Power  
To power the scanner from an AC outlet, use the provided AC  
adapter with a 5.5 mm outer diameter/2.1mm inner diameter tip.  
Caution: You must use a Class 2 power source that supplies 13.8 V DC and delivers at  
least 700 mA. The cord connector’s center tip must be set to positive and its plug  
must fit the scanner’s DC 13.8 V jack. Using an adapter that does not meet these  
specifications could damage the scanner or the adapter.  
• Always connect the AC adapter to the scanner before you connect it to AC power. When  
you finish, disconnect the adapter from the AC power before you disconnect it from  
the scanner.  
1. Insert the adapter’s barrel plug into the DC  
13.8 V jack on the back of the scanner.  
2. Plug the adapter into a standard AC outlet.  
Note: Use only the AC adapter supplied with  
your scanner.  
13.8V  
Connecting an External Speaker  
In a noisy area, an external speaker (available  
at a local electronics store) positioned in the  
right place might provide more comfortable  
listening.  
Plug the speaker cable’s 1/8 inch (3.5 mm) plug into your scanner’s EXT. SP. jack.  
Note: Connecting an external speaker  
disconnects the scanner’s  
internal speaker.  
Connecting an Earphone  
For private listening, you can connect an  
earphone with a 1/8 inch (3.5 mm) plug to the  
EXT. SP. jack on the back of the scanner. Be very careful as damage to your hearing  
can result if the VOLUME control is not set to the lowest level first. See below for  
"Listening Safely" instructions. (Your local electronics store should carry a wide selection of  
earphones.) Once the earphone is connected, it will automatically disconnects the internal  
speaker.  
 
17  
Listening Safely  
To protect your hearing, follow these guidelines when you use an earphone or headphones.  
Do not use the earphone to listen to the WX alert siren test or when in SAME Alert  
mode. The alert tone's volume is not adjustable and damage to your hearing could  
occur.  
• Do not listen at extremely high volume levels. Extended high volume listening can lead to  
permanent hearing loss.  
• Set the VOLUME to the lowest setting before you begin listening. After you begin listening,  
adjust the VOLUME to a comfortable level.  
• Once you set the VOLUME, do not increase it. Over time, your ears adapt to the volume  
level, so a volume level that does not cause discomfort might still damage your hearing.  
Connecting the Clone Cable  
You can transfer the programmed data to and from another BC796D scanner using a  
RS232C Cable (9 pin to 9 pin) (not supplied). Connect the cable between each scanner’s  
REMOTE jacks. See "Clone Mode" on page 73. You can also upload or download the  
programmed data to or from a PC using an optional PC interface kit available through your  
local electronics store.  
Connecting the Tape Recorder  
You can use a standard tape recorder or a VOX (Voice Operated Control) recorder. To  
connect the recorder to the scanner, connect a cable with a 1/8 inch (3.5 mm) plug from the  
tape recorder’s remote jack to the TAPE OUT jack on the back of the scanner. (Your local  
electronics store should carry a wide selection of cables and tape recorders.)  
Remember!  
• You must mark a channel, ID, talkgroup, or bank for Recording in order for this feature to  
work.  
• This feature does not work if your scanner is set with MUTE ON.

Basic Operation  
This section is your main reference for using the scanner once you have programmed  
conventional and trunked systems. Note that there are some slight differences to some  
functions depending on whether you are trying to affect conventional operation or trunked  
operation. Be sure to refer to the appropriate section depending on the mode you are using.  
Turning On the Scanner  
Turn the VOLUME control clockwise out of the detent position. The scanner automatically  
starts scanning. Since there are no frequencies programmed in your scanner initially, you  
may not receive any signals. Once you set the squelch and program some frequencies, you  
will begin hearing conversations regularly.  
Setting the Squelch  
To set the squelch, you must be in the hold mode, and you should not be receiving a signal  
on your scanner.  
1. Press /HOLD until you do not hear a signal.  
STRONG SIGNALS  
2. Make sure that the VOLUME is set to a comfortable listening  
MEDIUM SIGNALS  
level.  
WEAK SIGNALS  
3. Think of the Squelch Control as a gate. Turn the SQUELCH  
control fully counterclockwise. This raises the “Squelch Gate” so  
high that only very strong signals can get through.  
NOISE  
4. Turn SQUELCH clockwise until you hear a hiss. This lowers the  
STRONG SIGNALS  
“Squelch Gate” so that everything gets through – noise, weak  
signals, medium signals and strong signals.  
MEDIUM SIGNALS  
WEAK SIGNALS

Using the Menu  
Many of your scanner’s functions are accessed through its menu system. For complete  
information about a menu option, see the section referencing its use. A complete list of the  
menu structure is included in the back of this manual. To select a menu item, first press  
MENU to go to the first-level menu. Then, either press the number key corresponding to the  
option you want to select, or use the scroll bar to highlight the option then press E.  
To back up a menu level, press MENU.  
Notes: • To change a setting that affects either a specific bank or channel, first select a  
channel within the bank or the channel that you want to modify.  
• To check the settings for a channel, press and hold MENU for 2 seconds.  
In this manual, we represent navigation through the menu with the following nota-  
tion:  
MAIN MENUSUB MENU 1SUB MENU 2  
For example to access the DIMMER LIGHT option, the notation is:  
3:SYSTEM OPTION 1:DIMMER  
To access this option, press MENU, then scroll to each menu option and press E.  
Or, press MENU, 3, 1.  
• Some menu items are not numbered. To access these options, you must manual-  
ly navigate to the selection using the scroll bar.  
Manually Selecting a Channel  
To manually select a channel, press /HOLD, the channel number, then /HOLD again.  
The scanner displays the information stored in that channel.  
Notes: • If the channel contains trunked system information, frequency data is not dis-  
played.  
• If you are trunk scanning, you need to first press TRUNK to exit the trunking  
mode.  
Scanning Programmed Channels  
Before you can scan, you must first program channels. See the appropriate programming  
section for complete instructions.  
To begin scanning, simply turn on your scanner or, if the scanner is not currently scanning,  
press SCAN. The scanner checks each system you have programmed that is not locked out  
and stops if there is activity. SCANscrolls across the display, right to left.  
When the scanner receives a signal on a programmed channel, it stops on that channel and  
displays the channel information (text tag, channel number, trunk mode).  
Locking/Unlocking Banks  
When you are scanning conventional banks, the scanner displays the digit corresponding to  
all unlocked banks. To lock out a bank so that the scanner does not scan its channels, press  
the number that corresponds to the bank. The scanner replaces that bank’s number with a  
dash.  
 
20  
To unlock locked-out banks, simply press that bank’s number again. The scanner displays  
that bank’s number and includes it when scanning.  
Note: You cannot lockout all banks. One bank must be unlocked at all times.  
Locking/Unlocking Channels  
To lock out a channel so that the scanner does not stop on it while scanning, press L/O  
when the scanner is stopped on that channel or manually select the channel and press L/O.  
To unlock the channel, manually select it and press L/O again.  
Note: You cannot lockout all channels in a bank. One channel must remain unlocked. If you  
want to lock out an entire bank, see the previous section.  
Restoring All Locked Out Channels  
To simultaneously unlock all channels, press /HOLD, then press and hold L/O for 2  
seconds. The scanner beeps twice and unlocks all channels.  
Priority Scanning  
When Priority Scan is turned on, the scanner checks the conventional priority channels in  
the unlocked banks every 2 seconds or the priority ID’s in trunked systems every 4 seconds  
between transmissions. If a signal is present on a priority channel, the scanner switches to  
monitor that transmission, even if it had been stopped on another channel. One channel or  
talkgroup ID in each bank is designated as the priority.  
To turn on Priority Scan, repeatedly press PRI until the scanner displays PRIORITY ON. To  
turn Priority Scan off, repeatedly press PRI until the scanner displays PRIORITY OFF.  
Note: If all priority channels in unlocked banks are locked out, the scanner displays ERROR  
when you try to turn on the priority scan mode.  
Priority Plus Scanning  
To scan only the priority channels in the unlocked banks, while scanning repeatedly press  
PRI until the scanner displays PRIORITY PLUS. To turn off Priority Plus, repeatedly press  
PRI to select PRIORITY ON or PRIORITY OFF.  
Note: Priority Plus only operates in the scan mode; not in the hold or search mode.  
Listening to the Input Channel  
Repeater-based systems, such as public safety conventional, trunked systems, and some  
other business and amateur radio systems, use two sets of frequencies – input frequencies  
and output frequencies (see “Understanding Scanning”). You normally listen to the output  
frequency, as it can generally be received from a much farther range. Sometimes, though,  
you might want to know if the mobile unit is nearby. To do this, check the input frequency by  
pressing RVRS. If you hear the transmission, then the mobile unit is probably within 2 or 3  
miles of your location.

Muting All Audio  
To mute all audio, press and hold MUTE for 2 seconds. The scanner operates normally, but  
no audio sounds from the scanner. To turn audio back on, press and hold MUTE for 2  
seconds.  
Setting Squelch Mode  
You can set the scanner to either stop on any transmission during searching or scanning, or  
only stop on transmissions that include a specific CTCSS or DCS subaudible tone (see  
“Understanding Scanning” for information about subaudible tones).  
3:SYSTEM OPTION 8:SQ MODE  
1:CSQ  
Carrier Squelch mode; the scanner stops on any transmission regardless of whether  
a subaudible tone is present.  
2:TONE SQ  
The scanner stops on transmissions that include a matching subaudible tone or  
have no tone at all. When you select this option, you also need to set the  
appropriate tone in either the channel memory or for the search range.  
3:TONE SEARCH  
When the scanner stops on a transmission, it will then scan the subaudible tones to  
determine the correct setting. When the scanner has found the correct tone, it  
flashes the tone on the display. If you store that frequency into a channel, the tone  
is also stored.  
Trunk Scanning Options  
When you are scanning a trunked system, there are several trunking-only options available  
to you. This section outlines these options.  
Searching for Active Talkgroups (ID Search)  
If you want to hear all activity on a system, use the ID Search mode. While scanning a  
trunking system, press SRCH while scanning that system; or, press and hold TRUNK until  
the scanner flashes READY TO ID SEARCH. The BC796D stops on every active  
talkgroup, regardless of whether you have programmed it into your scanner.  
Notes: • If you have not yet programmed any ID’s for the system, this is the only mode  
available.  
 
23  
• In the ID search mode, the scanner displays the alpha tags associated with the  
stored talkgroups or NEW for talkgroups you have not stored.  
Scanning Only Stored Talkgroups (ID Scan)  
To scan only those talkgroups you have stored into your scanner, press SCAN while  
scanning that system; or, press and hold TRUNK until the scanner displays READY TO  
ID SCAN. When one of the talkgroups you have stored becomes active, the scanner  
switches to that transmission and displays the ID number and the alpha tag for that talk  
group.  
Note: You must store at least two talkgroup IDs in the system for ID scanning to work.  
Monitoring Talkgroup ID’s  
To see all of the ID’s that are active on the system, while monitoring a trunked system press  
TRUNK. The scanner stops trunking the system and instead holds on the system’s control  
channel. You hear the control data and the scanner displays every talkgroup ID as it  
becomes active in the system. To resume trunktracking, press TRUNK again.  
Selecting Talkgroup Lists to Scan  
When the scanner is in the ID Scan mode, you can select which ID lists you want the  
BC796D to scan. First, if you are scanning a Motorola or EDACS system, ensure that you  
are in the Scan List mode. Press RVRS until the scanner displays “List” at the left side of  
line 3 in the display when it has not stopped on a talkgroup or on the left side of line 4 if it  
has stopped on a talkgroup. Then, press the number corresponding to the ID list you want to  
turn on or off.  
Holding on a Single Talkgroup  
To hold on an active talkgroup when scanning or searching, press /HOLD. The BC796D  
stops scanning and holds on the current trunking system. It only receives transmissions on  
the talkgroup that was active when you pressed /HOLD  
To select a talkgroup to hold on when that talkgroup is not active, you must first program  
that talkgroup into an ID list. Then, while scanning that system, use the scroll bar to select  
the talkgroup ID to hold on.  
To select a talkgroup to hold on when that group is not active, while ID scanning or ID  
searching the system, press /HOLD. Then, either enter the ID or (if you have stored the  
ID) scroll to the ID you want to hold on.  
Locking Out Talkgroups  
Like conventional scanning, you can lockout unwanted talkgroup traffic on trunking systems.  
This is particularly important if you are ID Searching a trunking system, as many systems  
share both voice traffic (that you usually want to hear) with some data traffic from water  
meter systems, door alarms, traffic signals and other data sources that you don’t want to  
hear.  
To lockout a talkgroup, press L/O when the scanner stops on that group. Or, if you have  
stored the talkgroup in an ID list, select that ID and press L/O.  
To unlock a talkgroup stored in a scan list, use the scroll bar to manually select that ID, then  
press L/O to unlock it.  
 
24  
To unlock an ID you locked out during ID search or ID scan:  
2:SCAN OPTION 2:TRUNK Select the Bank 7:L/O ID REVIEW  
Then, use the scroll bar to select the ID you want to unlock and press L/O.  
Or, press /HOLD then press L/O for 2 seconds to clear all the lockouts from the system.  
EDACS Blockout  
This is a powerful form of lockout that is only available for EDACS systems. EDACS  
Blockout lets you lockout entire Agencies or Fleets, not just individual talkgroups. To use  
blockout, while scanning an EDACS system, press /HOLD then press L/O for 2 seconds to  
clear all the lockouts from the system. Then enter the agency or the agency and fleet and  
.
.
press  
then L/O. For example, to lockout agency 4, press 04  
L/O.  
Unlocking All Talkgroups  
To unlock all talkgroups for a system:  
2:SCAN OPTION 2:TRUNK Select the Bank 7:L/O ID REVIEW  
Then, use the scroll bar to select the ID you want to unlock and press L/O.  
Or, press /HOLD then press L/O for 2 seconds to clear all the lockouts from the system.  
EDACS Patch Tracking  
EDACS systems sometimes bring several talkgroups together in a ‘Patch’. A patch might be  
used by a police agency at night to provide a single channel with a single dispatcher for a  
wide area. A patch is created when a single, temporary talkgroup substitutes for the original  
talkgroups. While the patch is running, which may be for hours or days, the original  
talkgroups cease to be used. If you were monitoring one of these talkgroups, you might think  
there was no traffic, but in fact the talkgroup was operating at the different temporary  
number.  
If a talkgroup in your Scan List is patched, your scanner will continue to receive it under its  
new identity until the patch has ended. When a patch is being received, the radio will display  
PATCH ID, and will show the temporary common talkgroup plus all the included  
talkgroups in a cycling display. The BC796D is limited to following one patches. The  
temporary talkgroups used for patches are usually found in AFS code 15-xxx, and  
sometimes 00-xxx.  
 
25  
Searching  
Your BC796D includes powerful search features that let you discover new active frequencies  
in your area. You can save up to 10 custom search ranges in your scanner. This section  
details how to use custom search ranges and also details the various settings that affect  
search operation.  
To start a search, first program one or more search ranges (see “Setting a Search Range”).  
Then, press SRCH. The scanner begins searching within the selected search range. To  
change to a different search range, press the number button associated with that range.  
By default, your scanner only searches one range at a time. To search multiple ranges, turn  
on Chain Search (see “Setting Chain Search”). When you turn on Chain Search, each time  
you press a number button, the associated range is turned on or off. Note that you must  
have at least one range turned on at all times.  
Holding on an Active Frequency  
To hold on the current frequency, press /HOLD. To resume searching, press RSM.

The scanner normally stops on any frequency with activity, and remains there until either the  
activity stops or you press RSM or use the scroll bar to resume scanning. However, some  
signals are identifiable by the scanner as data signals, and you can set the scanner to  
automatically skip these channels.  
3:SYSTEM OPTION 7:DATA SKIP  
1:ON  
The scanner skips data frequencies.  
2:OFF  
Data skip is turned off.  
Note: Even with this option turned on, the scanner might pause for a couple of seconds on  
data transmissions before resuming.  
Skipping Frequencies  
If a particular frequency continues to interrupt search scanning, it is possible to set your  
scanner to skip the frequency.  
 
26  
To skip over a frequency, press L/O when the scanner is stopped on a frequency you want  
to skip.  
Notes: • You can program up to 200 skip frequencies. The 201st skip frequency entered  
causes the first skipped frequency to unlock.  
• If all frequencies in the search range are set to skip, a beep sounds and it moves  
to Search Hold mode. To resume searching:  
1) Unskip all skipped frequencies  
—- OR —-  
2) Select a different Search Frequency range.  
To unskip all skipped frequencies, press and hold L/O for 2 seconds in Search  
Hold mode.  
Storing Found Frequencies  
If you find a frequency you want to save into a channel, simply press TRNFR when the  
scanner is stopped on that frequency. The scanner displays the lowest-numbered empty  
channel. Use the scroll bar to select the channel you want to save the frequency into, then  
press E.  
Notes: • If you have already stored this frequency, the scanner displays WARNING  
DUPLICATE and the channel where the frequency is stored. To store the frequen-  
cy anyway, press E again.  
• After you store the frequency, the scanner resumes searching.  
• If all channels are used, the scanner defaults to the last-used channel prior to enter-  
ing the search mode.  
Automatically Storing Frequencies  
During searching, you can have the scanner automatically store active frequencies into a  
bank you choose.  
1:SERVICE OPTION :CHAIN SEARCH 7:AUTO STORE  
1:ON  
1. Press the numbers corresponding to the banks you want the scanner to store found  
frequencies into.  
2. Press SRCH to start the auto-store operation.  
3. Press /HOLD to stop auto-store. The scanner exits the auto-store mode.  
Note: To ensure that you catch most active frequencies for the band, you should allow the  
auto-store operation to continue through at least a few complete sweeps of the band.  
Depending on the types of services, some occasionally active frequencies might not  
have activity for minutes or hours at a time.  
 
27  
Setting Subaudible Tones for Searching  
You can set the scanner to only stop on transmissions that either have no subaudible tone  
or include a specified CTCSS or DCS tone during searches. This setting affects all search  
ranges. For this feature to work, you need to turn on the Tone Mode (see “Setting Squelch  
Mode”).  
1:SERVICE OPTION :CHAIN SEARCH 5:TONE DATA  
1:CTCSS  
Lets you set the CTCSS tone.  
2:DCS

3:OFF  
Does not use subaudible tones.  
Note: If, instead of pressing E to select a tone you press L/O, the scanner will stop on any  
transmission except for those with the selected tone.  
Searching for Subaudible Tones  
If you set the system tone option to 3:TONE SEARCH(see “Setting Squelch Mode”), the  
scanner will determine the correct tone for the received signal.  
Attenuating All Search Ranges  
If you are near a strong RF source, you might need to attenuate the input signal in order to  
search properly. To turn on this option for all search ranges:  
1:SERVICE OPTION :CHAIN SEARCH 4:ATTENUATOR  
1:ON  
The attenuator is turned on.  
2:OFF  
The attenuator is turned off.  
Setting DELAY for All Search Ranges  
You can set the scanner to have a delay after the end of a transmission before searching  
resumes. This slows searching, but helps you prevent missing replies on a frequency.  
1:SERVICE OPTION :CHAIN SEARCH 3:DELAY

Service Search  
The Service Search feature lets you scroll through the following twelve preprogrammed  
services. The frequencies selected for these services are the most commonly used around  
the U.S.  
1:WEATHER  
7:RAILROAD  
8:AIR  
2:PUBLIC SAFETY  
3:NEWS  
9:CB RADIO  
0:FRS & GMRS  
:RACING  
4:TV BROADCAST  
5:HAM RADIO  
6:MARINE  
:SPECIAL  
Note: Special Frequencies are low-power, itinerant, “splinters” and other frequencies which  
are commonly used at special events and other locations and may or may not be  
licensed.  
To access this feature:  
1. Press SRVC.  
––– OR –––  
Use the menu to select 1:SERVICE OPTION.  
2. Select a preprogrammed service to search by selecting from the Service Search menu.  
Note: Except for Weather, when you press E to select a service, searching begins  
immediately. For weather search options, see “Using Weather Search and  
Weather Alert.”  
Service Search Skip  
You can set the scanner to skip up to 100 unwanted frequencies during Service Search.  
To skip over a frequency, press L/O when the scanner has stopped at a frequency you  
want to skip.  
To restore a skipped frequency during search, press /HOLD select the desired  
frequency using the scroll bar, then press L/O.  
To restore all skipped frequencies, press and hold L/O for 2 seconds.  
Notes: • You can not skip frequencies in the Weather Service mode.  
• If you start Service Searching for a service that has all frequencies locked out,  
you hear a beep and the scanner moves to the Hold mode.  
 
31  
Using Weather Search and Weather Alert (SAME)  
Your scanner allows you to either search for a local NOAA weather broadcast, or be set to  
alert when a SAME weather alert is broadcast on a NOAA channel.  
Searching for a Weather Broadcast  
To search for a weather broadcast in your area:  
1:SERVICE OPTION 1:WEATHER 1:MONITOR  
The scanner begins to search the frequencies used by the National Weather Service for  
these broadcasts. When it finds a broadcast, it stops on the channel until you select another  
option or reception of the signal stops.  
Note: NOAA broadcasts are continuous broadcasts. You will only lose reception if you  
move out of a coverage area. If the signal is lost, the scanner resumes searching for  
a weather transmission.  
Using Weather Alert (SAME)  
Important: Your scanner has been primarily designed to be a radio scanner. While it  
incorporates weather alert as one feature, we strongly recommend that you not use the  
scanner as your sole means for receiving emergency alerts. Your local electronics retailer  
carries several weather radios specifically designed for this function.  
SAME (Specific Area Message Encoding) was adopted late in the last century to replace the  
wide-area alerts previously used. Weather alerts today are preceded by a digital packet that  
identifies not only the type of alert, but also the geographic location for the alert. Thus, it is  
possible for a weather broadcast that can be received across many counties to be targeted  
to a single county.  
To specify a county, SAME uses a standard established by the US Census bureau, called  
FIPS. The format of a FIPS code is:  
DSSCCC  
Where  
D = area subdivision (0=entire area)  
SS = State code (00=all states)  
CCC = County code (000=all counties)  
For example, the FIPS code for Tarrant County, Texas is:  
048439 (48=Texas; 439=Tarrant County).  
Some counties are further subdivided, in which cases, the first digit will be 0 for all  
subdivisions in the county and each subdivision will be labeled 1-9.  
To program your scanner to alert you when the weather service issues an alert, you must  
set the scanner to the alert mode, and then leave the scanner monitoring the weather  
service. You cannot scan and monitor for weather alerts at the same time.  
 
32  
To limit alerts to a specific area, you must also program in the FIPS code(s) for the area(s)  
you want to receive alerts for. The scanner can be set to either alert for all areas, or only the  
areas you have programmed. You can get FIPS codes for your area by calling the National  
Weather Service at 1-888-NWR-SAME or visit their web site at  
To program weather alert operation:  
1:SERVICE OPTION 1:WEATHER 2:ALERT  
1. Select 1:ONto turn on weather alert.  
2. Use the scroll bar to select either ALL FIPS or one of the 15 programmable FIPS  
positions.  
3. If you need to program a FIPS code, press E, then enter the code and press E again.  
4. Press MENU two times.  
5. Select 1:MONITOR.  
The scanner displays WX ALERT ON. All audio is muted until an alert is received.  
Note: If you lose power or turn off the scanner, the scanner keeps the weather alert mode.  
Warning: Never listen to the scanner using a headphone or earphone when you have put  
the scanner in the weather alert mode. The volume control is disabled in this  
mode, and the loud alert sound could damage your hearing.  
If an event is issued, the scanner displays the text for the event and sounds an alert. The  
alert sound used depends on the type of event received:  
Statements: 2-tone beep  
Watches:  
2-tone trill  
Warnings: Siren  
The chart in the back of this manual details the various events and the type of alert  
produced.  
Testing the Weather Alert  
To test the alert to see what each alert sounds like, monitor the weather mode, then press  
/HOLD. Hold PRI for 2 seconds to start the test. Press any key to exit the test. The  
scanner sounds each of the three alert types repeatedly.  
Warning: Never listen to the scanner using a headphone or earphone when you are testing  
weather alert. The volume control is disabled in this mode, and the loud alert  
sound could damage your hearing.  
 
33  
Programming Bank Information  
In addition to channel and trunking system information you program into each bank (covered  
in the following sections), this section covers general bank information.  
Bank Configuration  
Each of your scanner’s banks holds 100 channels that can be a mix of conventional (non-  
trunked) channels and one trunking system. Bank 1 holds Channels 001-100, Bank 2 holds  
Channels 101-200, and so on through Bank 0 which holds Channels 901-1000.  
Additionally, each bank that includes a trunking system can also hold up to 100 Talkgroup  
ID’s for that system.  
Assigning Bank Names  
To give a bank a name that the scanner displays when it stops on a channel in that bank:  
3:SYSTEM OPTION 9:BANK TAG  
1. Use the scroll bar to select the bank you want to tag, then press E.  
2. Use the scroll bar to select the letter, then press /HOLD to move the entry position one  
space to the right or press LIMIT/to move the entry position one space to the left.  
3. When you have entered the tag, press E to save the tag and return to Step 1.  
 
34  
General Programming  
This section includes procedures that apply regardless of whether you are programming  
conventional or trunked channels.  
Deleting Frequencies from Channels  
To delete a stored frequency, manually select the channel, then press 0 and E. The contents  
of the channel are erased.  
Transferring Channel Information  
To transfer settings from one channel to another:  
1. Manually select the channel with the information you want to transfer.  
2. Press TRNFR. The scanner displays the lowest-numbered empty channel. To select a  
different channel, use the scroll bar to select the channel.  
3. Press E. All channel information is stored in the target channel and deleted from the  
original channel.  
Note: Trunking system information is not transferred.  
Entering Alpha Information  
Your BC796D lets you assign text tags to banks, channels, talkgroups, and search ranges.  
Follow these steps to enter a text tag.  
1. Use the scroll bar to select the letter.  
2. Press /HOLD to advance to the next letter or LIMIT/to back up to a previous letter.  
3. When you have completed the text tag, press E to accept the entry.  
General Programming Tips  
• Do not program weather frequencies into channels. Since they have continuous broad-  
casts, your scanner will always stop on them. Use weather service search to access  
NOAA weather broadcasts.  
• Group related services into a bank. For example, program city trunk system in Bank 1,  
amateur radio in Bank 2, and so on.  
• To quickly program a series of channels, start with the lowest-numbered channel. The  
scanner automatically advances to the next channel by default when you complete pro-  
gramming a channel.  
• Make a programming plan before you sit down to program your scanner. Write down what  
frequency you will store in each channel, along with other system information. Or, use the  
supplied software to organize your information before you start. Keep a record of what you  
programmed in case you lose programming. This lets you more quickly program the scan-  
ner the next time.  
 
35  
• Entered frequencies are rounded off according to the step size for the channel.  
• When you store a new frequency in a channel, the text tag previously assigned to that  
channel is deleted.  
 
36  
Programming Conventional Channels  
Each bank can hold a mix of conventional channels plus one trunking system. This section  
describes how to store known frequencies into conventional channels. The first few sections  
are intended to be performed in the order indicated if you are entering information the first  
time. If you are editing existing information, manually select the channel, then use the  
complete menu process to access the information you want to change.  
Note: To quickly store only a frequency in a channel, manually select the channel, enter the  
frequency, then press E. Do not use this method for Trunking systems, however, as  
these systems require additional information to scan correctly.  
1. Select a Channel to Program  
To start, first select the channel you want to program:  
2:SCAN OPTION 1:CONVENTIONAL  
Enter the channel number, then press E.  
2. Enter the Frequency  
a. Press 1 or highlight 1:FREQUENCYand press E.  
b. Enter the frequency you want to program, then press E.  
Notes: • If the channel already had a frequency programmed, it appears above the prompt.  
• If you select a frequency that is not valid, the scanner displays ERROR OUT  
OF BAND. Enter a correct frequency to continue.  
• If you enter a frequency that has already been stored in the scanner, the scanner  
displays WARNING DUPLICATEand the channel number that contains the  
.
duplicate. To save the frequency anyway, press E. Otherwise, press  
to cancel  
and enter a different frequency.  
• If you change an existing frequency, all other information stored for that channel  
is deleted or set back to default values.  
3. Assigning a Text Tag  
a. Use the scroll bar to select the channel you want to tag, then press E.  
b. Use the scroll bar to select the letter, then press /HOLD to move the entry position one  
space to the right or press LIMIT/to move the entry position one space to the left.  
c. When you have entered the tag, press E to save the tag.

resumes. To hold on the transmission, press /HOLD during the 5-second pause.  
8: -10 SECONDS  
The scanner only stops on transmissions for 10 seconds, then automatically  
resumes. To hold on the transmission, press /HOLD during the 10-second pause.  
Setting the Subaudible Tone Option  
2:SCAN OPTION 1:CONVENTIONAL Channel No. 3:TONE DATA  
Some radio systems use special tones to prevent interference from other nearby systems  
operating on the same frequencies. When tones are being used, the radios only open  
squelch when a transmission with a matching tone is present on the frequency. Some  
services, such as FRS, GMRS, and Business Band refer to these tones as Quiet Codes,  
Privacy Codes, or similar and use a number to associate a particular tone. The table in the  
back of the manual provides a cross reference to common associations. For this feature to  
work, you need to turn on the Tone Mode (see “Setting Squelch Mode”).  
1:CTCSS  
Continuous Tone Coded Squelch System (CTCSS) is used with Amateur Radio,  
FRS, GMRS, Business Band, and other systems. When you select this option, the  
scanner only opens squelch when a matching CTCSS tone is present on the  
frequency.  
2:DCS  
 
38  
Digital Coded Squelch is similar to CTCSS, but instead of differentiating codes  
using frequencies, DCS always uses the same frequency but encodes it with a  
binary value. When you select this option, the scanner only opens squelch when a  
matching DCS value is present on the frequency.  
3:OFF  
The scanner opens squelch regardless of the presence of tones.  
Note: If, instead of pressing E to select a tone you press L/O, the scanner will stop on any  
transmission except for those with the selected tone.  
Setting Beep Alert  
2:SCAN OPTION 1:CONVENTIONAL Channel No. 4:BEEP  
ALERT  
1:ON  
The scanner sounds three alert tones when it stops on a transmission on this  
channel.  
2:OFF  
Beep Alert is off.  
Setting the Attenuator  
2:SCAN OPTION 1:CONVENTIONAL Channel No.  
5:ATTENUATOR  
If you are near a very strong signal source, the signal can overload the scanner’s RF front  
end, causing poor audio quality or missed reception.  
1:ON  
RF attenuation is on for the channel  
2:OFF  
RF attenuation is off for the channel  
Changing the Frequency Step  
2:SCAN OPTION 1:CONVENTIONAL Channel No. 6:STEPS  
The channel frequency step option controls the frequency step size used when you manually  
tune up or down from the frequency stored in the channel. Your BC796D is preprogrammed  
with the most common steps sizes for each band, so you seldom need to change this  
setting.  
1:5KHz  
Use 5 kHz steps  
2:6.25KHz  
Use 6.25 kHz steps  
3:7.5KHz  
Use 7.5 kHz steps  
4:10KHz

7:50KHz  
Use 50 kHz steps  
8:100KHz  
Use 100 kHz steps  
9:AUTO  
Automatically set the step size based on the band  
Setting the Modulation Mode  
2:SCAN OPTION 1:CONVENTIONAL Channel No. 7:MODE  
Radio transmissions are modulated in several different ways. The BC796D is able to  
demodulate the most common transmission types. Your scanner has the most common  
modulation mode preset for each band, so you seldom have to change this option. However  
there are occasional services that use a modulation mode that is not standard for that band.  
1:AM  
Amplitude Modulation  
2:FM  
Frequency Modulation  
3:WFM  
Wideband FM  
4:NFM  
Narrowband FM  
Setting Priority Channels  
You can set one conventional channel in each bank as a priority channel. When you turn on  
the Priority Scan option (see “Priority Scanning”), the scanner automatically checks these  
channels every 2 seconds to see if there is activity. If there is, the scanner immediately  
switches to the priority channel.  
Notes: • The scanner does not check priority channels in locked-out banks.  
• The scanner does not check priority channels if the channel is locked out.  
By default, the first channel of each bank is set as priority. To change the priority channel:  
1. Manually select the channel you want to set as priority.  
2. Press and hold PRI for 2 seconds. The scanner beeps and the new priority assignment  
is made.  
Note: To program priority talkgroup ID’s for trunk scanning, see “Setting Priority  
Talkgroups.”  
 
40  
Programming Trunked Systems  
Your BC796D is designed to scan most major types of trunking systems, including APCO  
Project 25 Phase 1 digital communication systems. These systems are briefly described  
here. For a more technical description of each system, see “Understanding Scanning.”  
General trunking options are also covered in this section. To program the systems, refer to  
the sections in the manual referenced below  
APCO Project 25 Phase 1 Systems — Digital systems that support the APCO Project 25  
protocol developed by the Association of Public Safety Communications Officials (APCO),  
the Telecommunications Industry Association (TIA) and Electronic Industries Alliance  
(EIA). Systems can operate in conventional, trunked (9600), trunked (3600) and mixed-  
modes (analog and digital) in any frequency band including UHF, VHF, 800 MHz, and 900  
MHz. See “Programming Motorola Systems.”  
MOTOROLA – Including Type I, Type II, Hybrid, SMARTNET, and Privacy Plus. Motorola  
systems are widely used by public safety and business users. Most are on the 800 MHz  
band, and recent systems are appearing on other bands. See “Programming Motorola  
Systems.”.  
EDACS – Including “Wideband” 9600 baud, and “Narrowband” 4800 baud systems.  
“Wideband” systems are mostly on the 800 MHz band, and are used by public safety, utili-  
ties, and business users. Some systems are used on the VHF and UHF bands.  
“Narrowband” systems are used in the 935-940 MHz band, many by utilities. See  
“Programming EDACS Systems.”  
EDACS SCAT – These systems are mainly used in the Midwestern United States and are  
one-channel trunking sites using the EDACS format. See “Programming EDACS  
Systems.”  
LTR – These systems are mostly for business users, and found on the UHF, 800 and 900  
MHz bands. See “Programming LTR Systems.”  
When tracking these types of systems, remember these important points:  
• Your scanner defaults to monitor Motorola Type II systems; however, you can change this  
if the system in your area is different.  
• The frequencies for many of the trunked public safety systems are listed in the  
TrunkTracker National Public Safety Trunked System Frequency Guide included with your  
BC796D scanner. Frequencies sometimes change, check with scanner.uniden.com for the  
latest information.

Setting Trunking Delay  
Setting a delay for trunking systems helps to ensure that you do not miss replies while  
scanning.  
2:SCAN OPTION 2:TRUNK Select the bank 4:DELAY  
1:NONE  
The delay is turned off.  
2:1 SECOND  
The delay time is 1 second.  
3:2 SECONDS  
The delay time is 2 seconds.  
4:4 SECONDS  
The delay time is 4 seconds.  
5:INFINITE  
When the scanner stops on a transmission, you must press RSM to resume  
searching.  
6: -2 SECONDS  
The scanner only stops on transmissions for 2 seconds, then automatically  
resumes. To hold on the transmission, press /HOLD during the 2-second pause.  
7: -5 SECONDS  
The scanner only stops on transmissions for 5 seconds, then automatically  
resumes. To hold on the transmission, press /HOLD during the 5-second pause.  
8: -10 SECONDS  
The scanner only stops on transmissions for 10 seconds, then automatically  
resumes. To hold on the transmission, press /HOLD during the 10-second pause.  
Using I-Call (Motorola and EDACS only)  
I-Calls are direct unit-to-unit transmissions that are not heard by other users. Your BC796D  
can monitor these transmissions in either the search mode or (if you have stored the unit  
number as a talkgroup) in the scan mode.  
When the scanner stops on an I-Call, the scanner displays the individual radio unit ID  
instead of a talkgroup ID.  
EDACS or Motorola Type 1  
Motorola Type 2  
i nnnnn  
7 nnnnn  
Note: • Each radio in a system has its own unique unit ID. Unit ID’s are not published for  
systems, and since officers might not use the same radio every day, it is difficult  
to predict who and what you will hear for a specific radio ID.  
• Since a conversation consists of two or more radios, and each radio has its own  
ID, if you hold on an I-Call, you will only hear one side of the conversation.  
Turning I-Call On and Off for ID Search  
2:SCAN OPTION 2:TRUNK Select the bank 9:I-CALL  
1:ON  
 
42  
The scanner will stop on I-Calls or normal talkgroups.  
2:OFF  
The scanner ignores I-Calls.  
3:ONLY  
The scanner only stops on I-Calls.  
Turning I-Call On for ID Scan  
.
To receive I-Calls for ID Scan, simply store the radio unit number as ( ) plus the unit  
number in place of the talkgroup. To receive any I-Call while scanning, enter the I-Call  
.
wildcard ( ) 0. For EDACS and Motorola Type 1 systems, this appears as i0; for Motorola  
Type 2 systems, this appears as 700000.  
Setting Priority Talkgroups (Motorola and EDACS only)  
Talkgroup priority works slightly different than conventional priority. With talkgroup priority,  
the priority talkgroups are only checked when the scanner is on the control channel. So, if  
you have delay turned on for the system or are holding on an ID, the scanner will  
immediately switch to the priority talkgroup if it becomes active during the delay or while  
there is no transmission on the held talkgroup.  
To assign a talkgroup as the priority talkgroup, select it in Scan Hold mode (see “Holding on  
a Single Talkgroup”). Then, press and hold PRI for 2 seconds.  
Multi-Track  
The BC796D allows you to track more than one system at a time. Here are some highlights  
of this feature:  
You can actually track up to 10 trunking systems at one time.  
You can trunk, scan, or search and scan conventional frequencies at the same time.  
You can program conventional frequencies in the same bank as trunking systems.  
After the scanner finishes checking a trunked system for activity, it will conventionally  
scan the other frequencies in the bank (remember, only trunking frequencies are  
programmed in Trunk mode).  
To scan a mix of trunking and conventional banks, select the banks you wish to be active,  
and then press SCAN. The scanner will instantly begin scanning. If you have not  
programmed a trunking bank with talkgroup ID’s, you will receive NO ID (----)  
message for that bank.  
You can switch to Search mode and the scanner will search for any active ID’s on the  
system.  
Note: To switch ID Scan or ID Search, press and hold TRUNK or, press SCAN or SRCH  
while scanning.  
Multi-Track Operational Details  
When more than one trunk system is active (for example two or more trunked systems or a  
trunked system and one or more conventional frequencies), the radio jumps between  
systems/frequencies as follows:  
 
43  
TRUNK SCAN: The scanner moves to a trunked system and looks for IDs in your Scan  
List(s) for up to 1 second. If it finds no activity on your programmed talkgroups, it moves  
on to conventional channels in the same bank or to the next active bank.  
If the scanner finds that a talkgroup in one of your active Scan Lists becomes active, you  
will begin to hear that communication and the scanner will display the proper talkgroup  
number and any alpha tag. When the communication ends, the scanner will wait for 2  
seconds for any further replies and, if none, the scanner will move to the conventional  
channels in the same bank or to the next bank. The scanner will not look for any other  
IDs within the same trunked system (as this would slow the scan process). If you press  
RSM while you are listening to one ID, the scanner will check to see if another ID in your  
Scan List is active. It will disregard the ID to which you were just monitoring.  
TRUNK SEARCH: This mode works similarly to Trunk Scan. If the scanner finds any (non-  
locked-out) ID when it checks the control channel, you will hear it. You will then hear any  
replies that follow within 2 seconds. After that the scanner will move on and not  
continuously search the system for additional IDs (on busy systems you would never leave  
the system if this were the case). If you press the RSM key while monitoring one ID, the  
radio will check if any other IDs are active (it will disregard the ID you just left), and if none  
are active, it will move on.

Programming Motorola Systems  
Follow the instructions in this section to program information for Motorola Type I, II, IIi  
Hybrid, and APCO 25 Digital trunking systems.  
Using Control Channel Programming  
Your scanner has a powerful feature that lets you program in only the control channels for  
Motorola 800 and 900 MHz systems. This can greatly shorten the time it takes to program  
system information.  
2:SCAN OPTION 2:TRUNK Select the bank :CNTRL CH ONLY  
For 900 MHz systems, you can then simply turn the feature on or off. For 800 MHz systems,  
you need to select the band plan for the system:  
1:PLAN1  
Use if the last three digits of all of the frequencies used by the system end in 125,  
375, 625, or 875.  
2:PLAN2  
Use if the highest frequency used by the system is above 866 MHz and if the last  
three digits end in 000, 125, 250, 375, 500, 625, 750, or 875.  
3:PLAN3  
Use if the last three digits of all the frequencies in the system end in 000, 250, 500,  
or 750.  
4:PLAN4  
Use if the highest frequency in the system is below 866 MHz and if the last three  
digits end in 000, 125, 250, 375, 500, 625, 750, or 875.  
5:OFF  
Select to turn off control channel programming for this bank.  
Note: • Many systems alternate control channels. To properly track the system, you need  
to program all alternate control channels.  
• If you do not know all of the frequencies for a system, but know at least one con-  
trol channel, start by selecting Plan 1 (the most common type). If you notice that  
you seem to be missing transmissions and replies, try each of the other plans  
until you find the one that works best.

“Programming Talkgroups.”  
 
47  
Toggling the Status Bit  
Motorola talkgroup ID’s are sent as a 16-bit binary number. Normally, the last 4 positions in  
the number are 0’s, which result in all talkgroups being equally divisible by 16. These last  
four bits, however, can be used by the trunking system to indicate various status conditions.  
For example, an emergency status could be indicated by setting the second-from last digit to  
1. Talkgroup 33264, then would be sent on the system as 33266 when the radio triggered its  
emergency status. By default, the BC796D ignores the last four digits of every talkgroup,  
effectively rounding them down to the nearest multiple of 16 regardless of the status bits.  
2:SCAN OPTION 2:TRUNK Select the bank 0:STATUS BIT  
1:ON  
Talkgroups are rounded down to the next multiple of 16.  
2:OFF  
Talkgroups are not rounded down, so you can determine the value of the status  
bits.  
Toggling End Code Detect  
At the end of each transmission, a digital burst is sent so that radios on the system will  
quickly switch back to the control channel. Your scanner also listens for this code.  
2:SCAN OPTION 2:TRUNK Select the bank :END CODE  
1:DETECT  
The scanner detects the end code and immediately switches back to the control  
channel.  
2:IGNORE  
The scanner waits for the carrier to drop before switching back to the control  
channel.  
 
48  
Programming EDACS Systems  
Follow the instructions in this section to program information for EDACS Wide, EDACS  
Narrow, and EDACS SCAT trunking systems. Note that to program these systems, in  
addition to knowing the system type and frequencies used, you must know the logical  
channel numbers (LCN) for the system’s frequencies. This information is usually provided  
with the frequency and other information. For more information refer to “Understanding  
Scanning.”

Programming APCO 25 Systems  
To program an APCO 25 system, follow the steps in the appropriate section for conventional  
or Motorola Trunking. APCO 25 systems require only 1 additional setting: Sound Quality.  
Setting APCO 25 Sound Quality  
Each APCO 25 system has slightly different system settings that control how the audio is  
digitized. To get the best sound quality, you need to match as closely as possible the  
system’s settings.  
To adjust the sound quality:  
1. While monitoring a specific APCO P-25 talkgroup, press the /HOLD key.  
2. Press and hold the 9 key. On Line 1 of the screen you will see SOUND QULTY:  
0050(for example). This shows the Sound Quality. The lower the level the better the  
Sound Quality.  
3. To manually set the sound quality, rotate the scroll bar up or down. As the threshold  
adjusts in increments of 100 at the bottom of the screen watch the Sound Quality level  
increase or decrease and continue to rotate the VFO until you have achieved the best  
Sound Quality level.  
Notes: • When APCO P-25 signal is not received, SOUND QULTY: ****appears  
on the display.  
• You must be receiving an APCO P-25 signal to make this adjustment

Glossary of Terms  
Alpha tag - This term refers to an alphanumeric text tag that you can enter to describe the  
individual frequencies that you have programmed. Rather than having to associate a spe-  
cific frequency to the individuals that are using it, you can enter the actual name of the  
group. This will eliminate the need for memorizing the group’s frequency.  
Attenuator - This scanner comes with a feature to attenuate or reduce the signal strength.  
The built-in attenuator can be turned on specific frequencies to prevent strong signals from  
overloading the scanner input, possibly damaging the scanner or missing other transmis-  
sions due to the repeated stopping on the stronger signal.  
Clone - This term identifies the ability to set up a duplicate scanner. This function allows  
you to clone all the programming information, including frequencies, talkgroups and alpha  
tags as well as bank settings and other parameters from one BC796D to another or  
BC296D.  
Control Channel - This is the frequency within a trunking system that runs the system. On  
Control Channels (sometimes called Data Channels) you will hear a buzz saw sound. For  
the most part, it is the sound of the system’s central computer directing talkgroups to  
particular voice (working) frequencies within the system.  
CTCSS - (Continuous Tone Controlled Squelch System) refers to a system where the radio  
receivers are equipped with tone responsive devices which allow audio signals to appear  
at the audio output, select voice processing such as scrambling or control repeater func-  
tions only when a carrier modulated with a specific tone is received. This method may be  
used to restrict access to the repeater or receiver, or reduce interference where several  
stations with output frequencies in close proximity of each other make it difficult to hear  
the conversation you are interested in. With CTCSS squelching, you can eliminate the  
possibility of hearing unwanted conversations by selecting one of the 38 standard subaudi-  
ble tones. You will only hear those transmissions that have been programmed on specific  
frequencies with the specific subaudible tone that you have selected.  
DCS - (Digital Controlled Squelch) refers to a system where the radio receivers are  
equipped with data burst responsive devices which allow audio signals to appear at the  
audio output, select voice processing such as scrambling or control repeater functions only  
when a carrier modulated with specific data burst is received. This method may be used to  
restrict access to the repeater or receiver, or reduce interference where several stations  
with output frequencies in close proximity of each other make it difficult to hear the  
conversation you are interested in. With DCS squelching, you can eliminate the possibility  
of hearing unwanted conversations by selecting one of the 104 standard data burst  
subaudible tones. You will only hear those transmissions that have been programmed on  
specific frequencies with the specific subaudible tone that you have selected.  
Enter Lock - This is the term used for locking the keypad. This prevents accidental re-pro-  
gramming of channels and talkgroups entered into memory. The default setting is OFF.  
When ENTER LOCK is enabled, the following functions will be disabled:  
• Enter or modify the Memory Channel frequency  
• Enter or modify the Tone information  
 
61  
• Enter or modify the Trunking ID. ( this can be modified  
through the menu screen.)  
FIPS Codes - For the purpose of broadcasting weather information, the NWS (National  
Weather Service) has divided the United States into regions by state and county (or  
parish, where applicable) then assigned a 6 digit FIPS code to identify each county or  
parish. The first digit represents the county subdivision, the next two represents the state,  
and the last three digits represent the county or parish. Your scanner can receive all  
SAME alert signals broadcasted within about a 50-mile radius of where you install it. So if  
you only want to hear the counties that are nearest to your area, you can choose  
specifically the FIPS code of areas that you want. This lets you avoid hearing warnings  
that apply to an area within a 50-mile radius but not necessarily in your county or parish.  
I-Call - Most communications within a trunked system are group calls where one unit (such  
as a dispatcher) communicates with all the units within her group (all the patrol vehicles on  
the east side of town, for example).  
The units within this group comprise what is typically known as a talkgroup. There are  
some communications which are direct unit-to-unit conversations where one individual  
converses with another individual. The call is initiated by a radio and is directed to another  
single radio. Within the system, no one outside of these two users hears the conversation.  
This call is referred to as I-Call.  
Key Beep - This is another term for the tone you hear as a keypad acknowledgement beep.  
The default setting is on.  
If you have turned the Key Beep off, you now have a silent keypad. You will not hear a  
tone each time you press a key.  
NWR S.A.M.E. Weather Alert - In 1994, the National Oceanic and Atmospheric  
Administration (NOAA) began broadcasting coded signals called FIPS (Federal  
Information Processing System) codes along with the standard weather broadcasts for  
stations in your area. These codes identify an emergency and the specific geographic  
area (such as your county) affected by the emergency. The scanner was developed with  
SAME (Specific Area Messaging Encoding) technology.  
This allows you scanner to receive, interpret, and display the information about the codes  
so you can determine if the emergency might affect you area.Each FIPS code identifies a  
specific geographic area (defined by the National Weather Service) so your scanner  
sounds an alert only when a weather emergency is declared in those locations.  
This helps you more efficiently track the weather conditions in and around your area.  
PC Control - This term is associated with the ability to program frequencies and other  
useful information via a computer by means of third party software. You can change the  
transfer speed on the scanner needed to be compatible with your PC. (See page 55)  
Scan List - When you designate a bank to be a trunking bank, your scanner sets up 10  
Scan Lists, which are simply list of your favorite IDs. Each list can contain up to 10 IDs, so  
you can store a total of 100 IDs for each trunk bank. These lists are designed to help you  
organize the trunking system users into categories.  
Screen Mask - Screen Mask reduces the amount of information that appears on the  
display. Alpha tags that you have set for a channel along with a few function icons will  
appear only on the display. This mode is particularly useful in public safety vehicles where  
that are already overloaded with information. Screen Mask does not work in Search mode.  
 
62  
Status Bit - This term refers to Motorola Type II systems. There is a method by which  
special types of communications utilize unique talk group numbers.  
For example, if all emergency calls are set to occur on a specific talk group number then  
you will not miss the transmission even if you have not programmed all the talk group  
numbers. With the Status Bit on and you have programmed the unique number, then you  
don’t have to worry what the rest of the groups numbers are. The topic of interest will be  
picked up.  
Talkgroup - A group of users within a trunked system that communicates with one another.

User Defined Fleet Maps  
Type I Programming Information  
When a Type I system is designed, the address information for all the IDs are divided into 8  
equal sized blocks. When you program your scanner to track a Type I system, you must  
select a size code for each of these blocks. When you have assigned a size code to all 8  
blocks, you have defined the Fleet Map for the system you're tracking. Each size code  
determines the number of Fleets, Subfleets, and IDs each block will have. For example, a  
size code of "4" has one Fleet, which is divided into 16 separate Subfleets, and it has a total  
of 512 individual IDs.  
When a block is assigned a size code, the Fleet or Fleets created within the block are  
assigned a Type I ID. The way these IDs display on your scanner depends on the block  
number and the blocks size code. When a Type I ID displays, the left most digit represents  
the block which contains the ID. The next two or three digits identify which Fleet is active,  
and the last digit(s) identifies the Subfleet.  
Block  
(1 digit)  
Subfleet  
(1 or 2 digits)  
Which Fleet  
within the Block  
(2 or 3 digits)  
The details concerning how the size codes are selected by a Type I system designer are  
highly dependent on the specific needs of the systems users. Some organizations may want  
many subfleets with only a few radios each, while another organization may want only a few  
subfleets with many radios each. Your task is to program your fleet map with the same size  
code assignments as the trunked system. If you do this accurately, you'll track all the Fleet-  
Subfleet combinations used by the system. In other words, you'll hear complete  
communications while monitoring a trunked system.  
If you don't already know the size codes used, you'll have to guess at them. But since you  
don't have to figure out all the blocks at once, this isn't as hard as it seems. Select a size  
code for a block, and then press SCAN. Now listen to the communications. If you decide you  
are receiving most of the replies to the conversations with IDs assigned to the block you just  
programmed, then you've probably selected the right size code and can work on the next  
block of the map.  
Finally, for most public safety systems there are some size codes which are more common.  
SIZE CODE 3 and SIZE CODE 4 are probably the most common, followed by SIZE CODE  
10, SIZE CODE 11, and SIZE CODE 12.

Size Code Restrictions  
If you select SIZE CODE 12, 13, or 14, there are some restrictions as to which blocks can  
be used for these codes.  
• SIZE CODE 12 can only be assigned to Blocks 0, 2, 4, or 6.  
• SIZE CODE 13 can only be assigned to Blocks 0 and 4.  
• SIZE CODE 14 can only be assigned to Block 0.  
Since these SIZE CODES require multiple blocks, you will be prompted for the next  
available block when programming a Fleet Map. For example, if you assign Block 0 as an  
SIZE CODE 12, you will be prompted for Block 2, the next block available, instead of Block  
1. And if you assign Block 0 as SIZE CODE 14, you would not see another prompt because  
all available blocks have been used.

product to be free from defects in materials and craftsmanship with only the limitations or exclusions set

WARRANTY DURATION: This warranty to the original user shall terminate and be of no further effect  
12 months after the date of original retail sale. The warranty is invalid if the Product is (A) damaged or
