1 The FCC W ants Y ou T o 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.
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.
Introduction The BC796D APCO 25 Digital Trunking Scanner connects you to the exciting world of scanning. Capable of scanning conventional frequencies, analog trunking systems, and the most popular digital trunking systems, it is a great all-in-one solution to your scanning needs.
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.
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.
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.
Tr u n ked 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.
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.
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.
Getting More Information By itself, this manual really only provides part of what you need to know to have fun scanning – how to program and use the scanner. The two supplied Conventional and Trunking frequency guides will give you a good head start on the other part of what you need to know – what frequencies have interesting content.

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.
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.
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.
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.
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.
Dimmer Light Setting The Dimmer Light setting sets the brightness of the display backlight. 3:SYSTEM OPTION → 1:DIMMER 1:HIGH Set the backlight to the brightest setting 2:MEDIUM Set the backlight to.
Disabling the APCO25 Card If you are not in an area where there is an APCO 25 digital system, you can save power by disabling the APCO 25 (P-25) card. 3:SYSTEM OPTION → 0:P-25 CARD 1:ENABLE The card is enabled 2:DISABLE The card is disabled Muting All Audio To mute all audio, press and hold MUTE for 2 seconds.
• 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 t.
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.
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 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.
Setting Subaudible T ones 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”).
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.
30 Plan 1, so this setting should work in most cases. Note: This feature only works for 800 MHz and 900 MHz Motorola trunking systems. If the scanner detects a trunking control channel, it will begin to track that system. The scanner displays the talk group numbers as they become active.
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.
Using Weather Search and W eather 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.
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.
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.
35 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 .
• 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.
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.
3:DONE Exit the channel setting and menu mode. Setting the Delay 2:SCAN OPTION → 1:CONVENTIONAL → Channel No. → 2:DELAY The delay option lets you set a delay after a transmission for each channel. This slows down scanning, but helps to prevent missing replies.
39 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.
40 6:25KHz Use 25 kHz steps 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.
Programming T runked 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.
42 Setting T runking 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.
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.
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.
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.
3. Select one of the following trunk types for Motorola Type 2 or digital Systems: 1:TYPE2/P25 800 Motorola Type 2 or Digital systems in the 800 MHz band 3:TYPE2/P25 900 Motorola Type 2 or Digital systems in the 900 MHz band 4. Select the channel to store the information into.
47 5. Select the channel to store the information into. 2:TRUNK CHANNEL Use the scroll bar to select a channel within the bank to store a system frequency, then press E . 6. Store the channel information 1:FREQUENCY Enter the frequency for the channel, then enter an Alpha Tag for the channel.
T oggling 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.
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.
Setting EDACS Decimal Mode By default your scanner displays EDACS talkgroups in AFS format (see “Understanding Scanning”). However, you can use this option to display and enter talkgroups in digital format. 2:SCAN OPTION → 2:TRUNK → Select the bank → :EDCS ID FORM 1:AFS Display the talkgroup ID in Agency-Fleet-Subfleet (AFS) format.
51 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.
Programming L TR Systems Follow the instructions in this section to program information for LTR trunking systems. For more information about LTR systems, refer to “Understanding Scanning.” 2:SCAN OPTION → 2:TRUNK → Enter the bank → 1:TRUNK TYPE → 1:ON → 9:LT → 2:TRUNK CHANNEL 1.
Programming T alkgroups For many of the trunk scanning features to operate, you need to program the scanner with the talkgroup ID’s. Each bank can store up to 100 talkgroups in 10 ID groups of 10 talkgroups each. Group similar talkgroups together in the same ID group.
Deleting Stored T alkgroup ID’ s To delete a stored talkgroup ID: 1. While scanning a trunked system in the ID scan mode (see “Scanning Only Stored Talkgroups”), press ▲ /HOLD . Or, to use the menu system: 2:SCAN OPTION → 2:TRUNK → Select the bank → 3:TALK GROUP 2.
Using the Remote Interface You can connect your scanner to either a PC or another BC796D using the remote interface cable port. This allows you to either control and program your scanner using a PC and the supplied software and cable or clone the memory from one BC796D into another BC796D (gender changer/coupler required, not supplied).
56 During transfer both scanners display the following. When transfer is complete, the scanners display COMPLETE. Turn both scanners off and then back on to initialize them. If data transfer is not successful, the following message appears. To clear the error, press .
Care and Maintenance General Use • Turn the scanner OFF before disconnecting the power. • Always write down the programmed frequencies in the event of memory loss. • If memory is lost, simply reprogram each channel. The display shows 000.0000 in all channels when there has been a memory loss.
58 T roubleshooting If your BC796D is not performing properly, try the following steps. If you experience difficulty while in TrunkTracker mode, try the following steps. Problem Suggestion Scanner won't work. 1. Check the connections at both ends of the AC Adapter .
59 Problem Suggestion APCO P25 CARD NOT INSTALLED appear when the scanner is turned ON. Neither APCO P25 CARD INSTALLED 9600 SYSTEM nor APCO P25 CARD NOT INSTALLED appear when the scanner is turned ON. Scratchy or robotic sound is heard during communications.
Specifications Certified in accordance with FCC Rules and Regulations Part 15, Subpart C, as of date of manufacture. Channel: 1000 Banks: 10 (100 channels each) Service Bands: 12 preprogrammed search bands (including the NOAA Weather Service band) Frequency Range: 25.
Glossary of T erms 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.
• 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.
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.
