Introduction

The BC785D is a state-of-the-art Digital Capable radio with TrunkTracker III and automatic scanning capabilities. It can store frequencies such as police, fire/emergency, marine, railroad, air, amateur, and other communications into 10 banks of 100 channels for a total of 1000 channels. With the optional BCi25D, APCO P-25 Digital Card installed you can monitor Public Safety Organizations who currently use conventional, Trunked at 3600 and Mixed Mode APCO 25 systems. Use your new scanner to monitor: Police and Fire Departments (including rescue and paramedics) Trunking for: Motorola Type I Type II Type I & II: (Hybrid) EDACS Wide band Narrow band Scat LTR Digital Communication for: APCO Project 25 Conventional Tranked at 3600 Mixed Mode at 3600 NOAA Weather Broadcasts Business/Industrial Radio Utilities Marine and Amateur (ham radio) Bands Air Band And much more. The chart below identifies the scanner band numbers, the frequency range, the modulation mode and the default step size settings.

BC785D 11/8/2 1:01 PM Page 21
2:DELAY You can set delay for a trunk system on a bank by bank basis. If youve set delay for 1 second, then there will be a one second delay in Trunk Search for that bank and a one second delay for all the talkgroups you have programmed into Scan List memory. You cannot set delay individually by talkgroup. The default delay is two seconds. 3:TONE DATA You can set a CTCSS (analog) or DCS (digital) subaudible tone for a frequency. To do so you must have the SQ Mode in the System Menu set to Tone SQ. You can also program a subaudible tone easily by pressing the E key in Scan Hold mode after programming a frequency. This will bring up the Tone Data menu without having to navigate the Menu. By doing this you will receive all transmissions on the frequency, regardless of the subaudible tone, except the one which you have locked. Any transmissions with that tone will not be received. 4:BEEP ALERT You can set a Beep Alert on a per-channel basis to alert you when specific frequencies are active. For example, you may wish to be alerted anytime a mutual aid fire frequency is active. With Beep Alert, you will hear three beeps at the start of each transmission that you have flagged as such. You will also notice that as you scroll pass the flagged channel(s), you will hear three beeps. 5:ATTENUATOR The BC785D comes with an RF Attenuation feature. If you are near an unusually strong signal source, the signal may overload the scanner. The scanner may stop repeatedly on that signal and miss other transmissions. The RF Attenuation feature works in all modes and attenuates (reduces) the incoming signal strength to prevent stronger signals from overloading the scanner. 6:STEPS Your BC785D is programmed with default step sizes for each frequency range (see page 1). Steps are important if you are interested in using the VFO to tune off from a frequency programmed into memory or if you wish to program a frequency that the default step size will not accept. For example, in VHF Hi-band mode, the default step size between 148 and 162 MHz is 5 KHz. However, the FCC has recently instituted 7.5 KHz channel intervals. If you wish to enter 155.4075 into the scanner without changing the default step, the scanner will change the programmed frequency to 155.4100. Use the Menu to change the default step size to 7.5 KHz and then you will be able to enter 155.4075. 7:MODE Default Auto receive modes are also programmed into memory. AM for aircraft and CB bands, for example. All frequencies (other than audio TV broadcast) above 400 MHz are received in NFM mode which helps prevent adjacent channel interference. You can change the default settings on a per-channel basis with this Menu item.

Data Skip

A scanner will normally stop on any transmission it receives. This means the BC785D will occasionally stop on data signals and unmodulated transmissions. You can automatically skip many of these types SYSTEM OPTION of transmissions during search. To activate the Data Skip 5:PC CONTROL feature, enter into the Menu mode. 1. Press MENU.

6:CLONE 7:DATA SKIP

2. Select 3:SYSTEM OPTION / 7:DATA SKIP by rotating the VFO and pressing E. 3. Select 1:ON by rotating the VFO and pressing E. Remember! You can also use L or M instead of rotating the VFO. Also instead of pressing E, you can press the VFO control. When Data Skip is active, your scanner may pause momentarily on an unwanted signal but will resume searching in 2 or 3 seconds. The Data Skip feature is active as well as Scan mode and Service Search mode. Data Skip does not function during AM/WFM band Scan, Chain Search for AM/WFM band, or WX Search, Priority Scan, and Trunking mode.
BC785D 11/8/2 1:01 PM Page 38

Frequency Skip

If a particular frequency continues to interrupt search scanning, it is possible to set your scanner to skip the frequency. To skip over a frequency, press L/O when stopping at the frequency you want to skip or when in Search Hold mode. Note: 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) Cancel the Frequency Skip set. OR 2) Reset the Search Frequency range. To cancel all skipped frequencies, press and hold L/O for 2 seconds in Search Hold mode.

Programming and Receiving Digital and Trunked Systems
There are three steps for programming a trunked sytem: 1. Program the Trunk Type What type of system will the scanner be tracking, Motorola Type II, Type I, EDACS, LTR, etc. 2. Program the Trunked Frequencies Within a trunked system, the frequencies are shared among all the users, called Talk Groups. Within the bank you decide which channels to program the trunked frequencies. 3. Program the Talk Groups Within the trunked system, each agency or department is assigned a Talk Group ID. This ID must be programmed into the scanner in order for it to monitor that specific agency or department. When programming you decide which Location to program the Talk Groups. This is similar to how you program frequencies into channels. Here you need to program Talk Group IDs into Locations.
STEP 1: Selecting or Changing Trunking System Type
Before using the Trunk Tracking system, you must select the bank and trunk type. You can only track one trunked system per bank, total of 10 trunked systems. 1 Press MENU.
Remember! You can also enter the Trunk Tracking programming mode by pressing TRUNK. 2. Select 2:SCAN OPTION / 2:TRUNK by rotating the VFO and pressing E. 3 Select the bank number using the keypad or the VFO and pressing E.
C 001 OOOO.0000 1:TRUNK TYPE 2:TRUNK CHANNEL C 001 OOOO.0000 1:TYPE2:TYPE1
4. Select 1:TRUNK TYPE / 1:ON and the system type you want to track by rotating the VFO and pressing E.
For Type 1 System, you must enter the block and fleet numbers. Please refer to Programming a Fleet Map on page 64 for instructions. Remember! You can also use L or M instead of rotating the VFO. Also instead of pressing E, you can press the VFO control. STEP 1 is complete.

Note: Information on APCO P-25 Systems are referred to in APCO Project 25 Reception on page 68.
STEP 2: Programming Trunking Frequencies
After you finish selecting the bank and trunk type you want to track, store the frequencies in the channels for your selected bank in your scanner. Remember that you can only store one trunking system in each bank. Important: If you are programming an EDACS or LTR trunked system, you must enter the frequencies in a specific order. Check the frequency guide included with the scanner for the frequencies in your area. For additional frequencies, check the web sites listed on page 10. 1. Press MENU. 2. Select 2:SCAN OPTION / 2:TRUNK by rotating the VFO and pressing E. 3. Select the bank number by rotating the VFO and pressing E. 4. Select 2:TRUNK CHANNEL and enter the channel number by rotating the VFO and pressing E. 5. Select 1:FREQUENCY and enter a frequency for the trunked system using the keypad and pressing E. 6. Enter the alpha tag and pressing E. (See page 49). 7 You can also change the step size in this menu. (See page 93).

Note: To clear a mistake while entering the frequency, press. (decimal key) twice, and the display is cleared. If you enter a frequency which is out of the systems trunking range, a beep sounds and ERROR appears on the display.
C 010 0000.0000 ERROR OUT OF BAND
If you enter a frequency which has been stored in another channel, you will hear a beep and the channel stored displays WARNING (Refer to Duplicate Frequnecy Alert on page 27).
BC785D 11/8/2 1:01 PM Page 48
Remember! You can also use L or M instead of rotating the VFO. Also instead of pressing E, you can press the VFO control (except for ALPHA TAG setting). STEP 2 is complete.
STEP 3: Programming ID Scan Lists Manually Scan Lists
Each bank of your BC785D can be a trunk tracking bank and it can be a conventional scanning bank. When you designate a bank as a trunking bank, your scanner sets up 10 Scan Lists, which are simply lists used to store your favorite Talk Group IDs. Each list can contain up to 10 IDs, so you can store a total of 100 IDs for each trunk tracking bank. (1000 if you use all the banks as trunking banks!) Scan Lists help you organize the trunking system users into categories. For example, you might use List#1 for police IDs, List#2 for fire department IDs, List#3 for emergency medical service IDs, etc. Once IDs are stored in lists, you can scan them like you scan conventional frequencies and you can lockout any one (up to 9) of the 10 scan lists by pressing the corresponding numeric key. When an ID is active, the scan list number will appear on the display. You can program your Scan Lists either manually or during Trunking Search mode. Check the web site www.bearcat1.com/free.htm for a complete list of talkgroups for your area that you can program into your Scan Lists. In order to program Talk Group IDs, you must first complete Step1Selecting or Changing Trunking System Type, page 46 and Step 2 Programming Trunked Frequencies, page 47. 1. Press MENU. 2. Select 2:SCAN OPTION / 2:TRUNK by rotating the VFO and pressing E. 3. Select the bank number by rotating the VFO and pressing E. 4. Select 3:TALK GROUP by rotating the VFO and pressing E. 5. Select the ID location by rotating the VFO or using the keypad and then press E. You decide which location you want to place the Talk Group ID. M1-5 (The first number represents the Scan List number and the -----second number represents the Memory Location number.) (Direct entry method example: enter "1-5" by pressing 1,. (decimal key), 5.) ENTER ID 6. Select 1:ID by rotating the VFO and pressing E. 7. Enter the ID number. Note: After you have programmed the ID in a selected location, while still in the Menu mode, you can set your Alpha Tag (see page 28), or turn ON the Beep Alert for an individual talkgroup (see page 22).

Receiving Trunked Systems
When you have properly programmed all the frequencies for a trunked system, you can receive the system in several different ways. You will find that Search, Hold, Lockout, Scan and Delay are all similar to conventional scanning. ID SCAN lets you receive those talkgroups that you store in Scan Lists. ID SCAN HOLD lets you selectively listen to a talkgroup in your Scan Lists. TRUNKED SEARCH lets you hear all system talkgroup activity (unit-to-unit I-Calls may be received as well). This is the best way to get started. ID SEARCH HOLD works with Search mode to let you quickly freeze reception on an interesting transmission. Or you can manually specify a talkgroup with DIRECT ENTRY in ID HOLD. ID LOCKOUT works with Search and Scan to exclude talkgroups that you don't want to hear. ID DELAY works with each talkgroup to be delayed when the communication ends. The setting periods can be changed (See page 32).
When receiving EDACS systems, remember that Uniden's AFS talkgroups give you powerful flexibility. In a few key presses, you can specify a single talkgroup, a fleet, or an entire agency in all the above modes. Read the section "EDACS Reception" to understand how this works. Hint: If the scanner is not in the Trunking mode, you can enter the Trunk Programming mode by pressing TRUNK. Pressing TRUNK in the Trunking mode will move to the Scan Hold mode.
BC785D 11/8/2 1:01 PM Page 51

ID Scan Mode

1. Press SCAN to begin scanning the lists you have programmed. If you haven't programmed more than 2 IDs, ERROR appears on the display.
ID SCAN 867.9875 NFM List 1234567890
Hint: Press and hold RSM for 2 seconds, the scanner will move to the next trunking bank. 2. To remove a Scan List from active scanning, press the number of the Scan List on your keypad. The Scan List indicator turns Off, and the IDs in that list are not scanned. Note: One Scan List must always be active. If you try and deactivate all the Scan Lists, Scan List 1 will automatically be active. 3. To restore a Scan List to active scanning, press its number again. 4. Press SRCH to return to Trunk Tracking Search mode. Remember! When you press and hold TRUNK for 2 seconds, you can switch Trunk Tracking modes (Scan or Search). Note: While ID Scanning, to change all trunking banks to the Service Search mode, press SRVC. Selecting a Scan List is also possible in the Menu mode. (LTR only) ID SCAN appears on the display during Trunk Scan instead of simply SCAN.

The system users are given blocks of talkgroups. Sizes vary but most large cities and other agencies have blocks of 128 channels. Smaller cities have only 64 or 32 channels.

Motorola Reception

Motorola Tracking
There are really two types of Motorola trunking systems. These are usually referred to as Type I and Type II systems. Type I only occurs on some 800 MHz systems. All VHF, UHF and 900 MHz trunking systems use Type II. One important distinction between these two systems is the amount of data transmitted by each radio when its push-to-talk button (PTT) is pressed. Every radio in a trunked system is assigned a unique ID so the central site computer can identify it when its used. Both Type I and Type II systems place radios (or radio users) into groups, called talkgroups, and these talkgroups are also assigned unique IDs. Some radios have access to only one talkgroup, while others have access to many talkgroups. The talkgroup(s) each radio can access is called the radios affiliation(s). In a Type II system, when someone uses their radio, only the radio ID is transmitted when PTT is pressed, whereas in a Type I system the radio ID and its current affiliation are both transmitted when PTT is pressed. Why the difference? Type II systems are slightly more advanced because the central computer maintains a database which is used to determine each radios affiliation(s). Changes to a Type II system are easier than Type I because the system manager only needs to update the database instead of reprogramming individual radios. Another difference between the systems is that Type I systems are arranged in a FleetSubfleet hierarchy. For example, its possible for a city using a Type I system to designate 4 Fleets, each with 8 Subfleets. Their fleets might be the Police Department, the Fire Department, Utilities, and Administration. The Police may decide to further divide their fleet into subfleets such as Dispatch, Tactical Operations, Detectives, North, South, East and West Side Patrols, and Supervisors. All the available police radios would then be assigned to one of the police subfleets. Determining the exact Fleet-Subfleet hierarchy for a particular area is referred to as Fleet Map Programming, which is discussed further in this manual. The disadvantage of a Type I system is that when PTT is pressed, the brief burst of data must contain the radios ID and its Fleet and Subfleet. This is three times the amount of data a Type II system radio sends, and as a result Type I systems usually accommodate fewer users than Type II systems. Even though there are many Type II systems, Type I systems are still in use. There are also Hybrid systems which are a combination of both Type I and Type II. Your scanner defaults to monitor Type II systems, but its possible to select a Preprogrammed Fleet Map or create a Custom Fleet Map for your area. For VHF and UHF Type II trunking systems, you will need to know the base, spacing frequencies and offset channels. See page 65 for details.

BC785D 11/8/2 1:01 PM Page 64

Fleet Map Programming

If you have programmed a trunk tracking bank for Motorola press SCAN to start Multi-Track, you will see user IDs display on the display. Since the BC785D defaults to Type II systems, all the IDs will appear as numbers. However, if you notice a mix of odd and even user IDs, for example 6477, 2560, 6481, 6144, 1167, etc., then you are probably monitoring either a Type I or Hybrid systems. These systems are applied only when STATUS BIT is OFF (see page 66). You may also notice that you are missing responses when you hold on an active ID. Unlike Type II, Type I/Hybrid systems require a Fleet Map that sets specific Fleet-Subfleet parameters. It is easy to select a Fleet Map for your scanner; what is not always easy is selecting or programming a map that matches your particular area. There are 16 preset Fleet Maps listed in the appendix that you can choose, and these are usually a good place to start when setting up a Type I/Hybrid trunk tracking bank. If you choose a preset map and still have difficulty following complete conversations, then you'll have to program your own Fleet Map.
Selecting Preset Fleet Map
1. Select 2:TYPE1 for the Trunk Type. (Refer to "Selecting or Changing Trunking System Type" on page 46.)
M 001 867.8375 NFM 1:TYPE2:TYPE 1 M 001 867.8375 NFM SELECT FLEET MAP PRESET 1
2. Select the map you want to program by rotating the VFO and pressing E. The scanner returns to the other programming items.
Note: You will now begin to see Type I Fleet-Subfleet IDs. For example, 100-12, 100-9, 000-12, 400-8, etc. See "User Defined Fleet Maps in the Appendix" for more information about Type I IDs. How do you know if the preset map is correct? You will have to listen to see if you're following complete conversations. If not, you should try another preset map.

Programming a Fleet Map

You may want to read "User Defined Fleet Maps" in the Appendix before programming a Fleet Map. It contains a detailed explanation of Scanner Fleet Map Programming, as well as a table listing the Fleet Map Size Codes. 1. Select 2:TYPE1 for the Trunk Type. (Refer to "Selecting or Changing Trunking System Type" on page 46.)
M 001 867.8375 NFM 1:TYPE2:TYPE 1
BC785D 11/8/2 1:01 PM Page 65
2. Select USER CUSTOM by rotating the VFO and pressing E. 3. Select the size code for the first block by rotating the VFO. 4. Press E. The next available block displays. 5. Repeat step 3 and 4 until you have selected a size code for each block. For details about each size code, see "Fleet Map Size Codes" in the Appendix.
M 001 867.8375 NFM SELECT FLEET MAP USER CUSTOM M 001 867.8375 NFM BLOCK 0 SIZE CODE 0

Programming a Hybrid System
A Hybrid system is simply a Type I system with some blocks designated as Type II blocks. To program a Hybrid system, follow the steps listed in "Programming a Fleet Map" in the previous section. However, if you want a block to be Type II, select Size Code S-0. When you begin searching a trunking bank with a Hybrid Fleet Map, you will see both types of system IDs. That is, Type II IDs usually appear as an even number without a dash; Type I IDs appear as a three or four digit number, followed by a hyphen, followed by a one or two digit number.
Setting the Base, Spacing Frequencies and Offset Channel for Motorola VHF/UHF Trunked Systems
To properly track Motorola VHF and UHF trunked systems you must enter what is known as the base, the spacing frequencies and offset channels for each system. To find these out, check the scanner.uniden.com or www.bearcat1.com/free.htm and other web sites and frequency resources. To enter the Base, Spacing Frequencies and Offset Channel: (You can set up to three sets of these, but almost all systems only use one set) 1. Press MENU. 2. Select 2:SCAN OPTION / 2:TRUNK by rotating the VFO and pressing E. 3. Select the bank number by rotating the VFO and pressing E. 4.

Note: If the system is not tracking properly, you may need to try a new Base Frequency or Offset Channel or you may be missing frequencies from the system. You can set up to three Base, Spacing and Offsets for Motorola VHF/UHF trunked systems.

Toggling the Status Bit

On Type II trunking systems there is a method by which specialized types of communications utilize unique talkgroup numbers. An emergency call will occur on a unique talkgroup from its primary assignment, for example. Because the BC785D defaults to Status-Bit ON mode, you never need to worry about missing these transmissions. If you have programmed talkgroup 33264 into Scan List memory, for example, and there is an emergency call within the group, you will hear it on 33264. The only time you may wish to turn Status Bits OFF is if you're trying to figure out the proper Fleet Map of a Type I trunking system. To turn Status Bits OFF, enter into the Menu mode and select 2:SCAN OPTION / 2:TRUNK - select bank number - /0:STATUS BIT. (This feature does not apply to EDACS and LTR operation within the scanner.) Then rotate the VFO to change the setting (1:ON to 2:OFF) and press E to program your change.

Receiving Mode Selection

You can also set the receiving mode, AM or FM etc., in Conventional mode or Chain Search mode. See MODE in "Menu Description" for details.
Frequency and Channel Tuning with the VFO Control
The VFO knob can be used for stepping frequencies or through memory channels (for Conventional channels or Talkgroup ID Scan Lists). To switch the setting for the VFO control, press the VFO. This will change modes from Channel to Frequency or Frequency to Channel. 1. In Conventional mode, when the setting for the VFO is channel, rotate the VFO to move up (to step up through channels) or down (to step down through channels). If you are in Trunk Manual mode, you will step through Scan List memory locations. 2. In Chain Search mode, when the setting for the VFO is frequency, rotate the VFO to move up to step up through frequencies sequentially or to down to step down through frequencies. To change the step, you will need to go into the Chain Search menu and adjust the step for the desired memory location. Remember! When you set Additional Features through the menu screen, you can also use L or M instead of rotating the VFO. Also instead of pressing E, you can press the VFO control.

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. Always press each button firmly until you hear the entry tone for that key entry, unless you have turned 2:OFF the 3:KEY BEEP in the menu system.

Location

Do not use the scanner in high-moisture environments such as the kitchen or bathroom. Avoid placing the unit in direct sunlight or near heating elements or vents. If the scanner receives strong interference or electrical noise, move it or its antenna away from the source of the noise. If possible, a higher elevation, may provide better reception.

Cleaning

Disconnect the power to the unit before cleaning. Clean the outside of the scanner with a mild detergent. To prevent scratches, do not use abrasive cleaners or solvents. Be careful not to rub the LCD window. Do not use excessive amounts of water.

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 dont 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.
