6 Important Notice • This scanning radio has been manufactured so that it will not tune radio frequencies assigned by the FCC for cellular telephone usage.
7 T erminology What is Scanning? Unlike standard AM or FM radio stations, most two-way communications do not transmit continuously. The BC785D scans the Frequencies you have programmed into the Scanner ’ s channels you program until it finds an active frequency.
TrunkTracker III changes this! Not only does your new BC785D scan channels like a conventional scanner, it actually follows the users of a trunked radio system.
9 Feature Highlights • Trunk Tracking – Follow VHF High Band UHF 800/900MHz trunked public safety and public service systems just as if conventional two-way communications were used. • Digital Capable – With the APCO 25 Digital card (BCi25D) installed, you can monitor supported project 25 systems.
Where to Obtain More Information Before using your scanner, you must program frequencies into available channels. The Betty Bearcat Frequency Guide lists typical frequencies used around the U.S.A. and Canada that you may program into your new scanner.
11 Included with Y our Scanner Package If any of these items are missing or damaged, immediately contact your place of purchase or Uniden Customer Service at: (800) 297-1023, 8:00 a.
12 Setup 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.
13 T ypical Mounting Methods The BC785D 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.
Applying Power for V ehicle 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.
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.
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. The volume is not adjustable and damage to your hearing could occur. • Do not listen at extremely high volume levels.
Basic Operation T urn the Scanner On 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 be hearing conversations regularly.
18 Next you must program some frequencies (page 26). It is recommended that you read the next part "Understanding the Menu System" because it will assist you in accessing and understanding many of the features.
Menu Description and Numeric Keypad Equivalents Below are the Menu screens and a brief description or purpose of the feature. 1:SERVICE OPTION Service Search menus are preprogrammed services used around the U.S. 1:WEATHER 1:MONITOR When you select this mode, the preprogrammed NOAA weather channel begins to activate.
4:ALPHA TAG You can enter an Alpha Tag for any or all of the search ranges. 5:TRUNK During Chain Search mode, when the scanner finds an active frequency, the trunk tracking system will be active. Four frequency plans apply to the Control Channel Only feature (for details see page 66).
2:DELAY You can set delay for a trunk system on a bank by bank basis. If you ’ ve 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.
8:RECORD You can flag any channel for recording using this menu function. Use your own recording device plugged into the jack on the back of the scanner. 2:TRUNK Choose the Trunk bank. The following options are available for the selected trunk bank only.
6:ID LIST TAG Assign an alphanumeric tag to any or all of the 10 Scan Lists for the system. During ID Scan Mode, you will see the ID List Tag (on the bottom text line) along with any alpha tag you may have set for an ID. In Search mode, you will see any Bank Tag you have set.
0:STATUS BIT (MOTOROLA) On Type 2 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.
25 6:CLONE You can clone all the programming, including frequencies, talkgroups and alpha tags as well as bank settings and other parameters from one BC785D to a BC250D or another BC785D. 7:DATA SKIP A scanner will normally stop on any transmission it receives.
Programming Before the BC785D can begin conventional scanning, you must program a frequency into at least one channel. Repeat this procedure for each channel you want to program.
Note: • You can also ▲ or ▼ when selecting a channel. Press and hold ▲ or ▼ for 1second to move up/down more quickly. • To clear a mistake while entering the frequency, press (decimal key) repeatedly until the display is cleared.
28 T ransfer Frequencies You can transfer a frequency that has been stored in a channel to another channel. 1. Press ▲ / HOLD . 2. Press TRNFR , and the smallest empty channel number along with the frequency will flash on the display. 3. Press E and the frequency can be stored in this channel.
29 numbers and punctuation marks. 6. After entering the desired text, press E . ☞ Remember! To clear a mistake while entering the letters, press (decimal key) repeatedly until the display is cleared. Beep Alert The scanner can alert you with three beeps at the beginning of a transmission on an assigned frequency.
30 Scanning 1. After programming frequencies, simply press SCAN to begin scanning. During scanning, when you rotate the VFO , you can select the direction ( ↑ or ↓ ) you want to scan. 2. The bank indicators selected for scanning appear on the display, and the bank being currently monitored flashes.
31 Note : When in Hold mode, you can use the VFO to step up or down through the channels. You can also switch from stepping up/down through channels to stepping up/down through frequencies by pressing the VFO . Storing Frequencies During Scanning During Scanning 1.

Starting Chain Search 1. After setting the search ranges, select 1:SERVICE OPTION / :CHAIN SEARCH / 1:CHAIN SEARCH by rotating the VFO and pressing E .
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.
39 Auto Storing The scanner automatically stores active frequencies if its Auto Store feature is turned ON. But the frequencies already stored can not be stored. To make use of this feature, set a search range first (see page 36), then enter into the Menu mode.
• Tone Lock (out) mode For either a Memory channel or a Search Range, you can lock a particular subaudible tone by pressing L/O after scrolling to the desired tone. The scanner will stop on any transmission except those which may be using the locked subaudible tone.
41 Additional Menu Options for Searching Each of these additional menu options applys to all search ranges entered. If there is a range that you do not want an option to apply, then simply enter the range number on the numerical keypad. You will see the range number that you have selected disappears from the display.
Service Search The Service Search feature allows you to scroll through the following twelve preprogrammed services. The frequencies selected for these services are the most commonly used around the U.
43 During the search of one of the preprogrammed services, the lowest display line will indicate the service that you are searching. To stop the search, press ▲ / HOLD or LIMIT / ▼ . Rotate the VFO or using ▲ or ▼ to move up or down one programmed frequency or press RSM to resume searching.
T esting the Alert Siren To test and recognize the difference between the types of alert sirens, perform the following steps: 1. During WX Hold mode and when the WX ALT is OFF, press and hold the PRI key for 2 seconds until you hear the statement alert siren.
45 Digital and T runked Systems Your BC785D is designed to monitor APCO Project 25 digital communication systems (using optional BCi25D) and tracks three major types of trunked radio systems.
Programming and Receiving Digital and T runked 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.
Note: Information on APCO P-25 Systems are referred to in “ APCO Project 25 Reception ” on page 68. STEP 2: Programming T runking 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! You can also use ▲ or ▼ 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.
To enter a Type 2 Talk Group ID: 1. Enter the ID you want to store. 2. Press E . To enter a Type 1 ID: For a Type I ID, the block number, Fleet number and Subfleet number make up the Talk Group ID number. Please see page 87. 1. Enter the ID you want to store (ID = Block number + Fleet number + (decimal key) + Subfleet number).
50 4. Select 3:TALK GROUP and ID location number by rotating the VFO and pressing E . 5. Select 2:ALPHA TAG by rotating the VFO and pressing E . 6. The cursor appears on the display. Rotate the VFO to change letters, and press ▲ /HOLD or LIMIT/ ▼ to move right or left.
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. 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.
Press SCAN , and select the bank(s) you wish to receive, just as you select banks in conventional scanning and ID scanning. Hint: Press and hold RSM for 2 seconds, the scanner will move to the next trunking bank. Talkgroups display differently in Motorola, EDACS and LTR systems.
53 Note : If you Lockout an ID in Search mode, it is also locked out in Scan List mode. Conversely, if you Lockout an ID while in Scan List mode, it is locked out in Search mode. For information about Scan Lists see page 48. EDACS BLOCKOUT is a powerful form of ID LOCKOUT that can be used only with AFS and EDACS systems.
Reverse Key For Motorola and EDACS system; to change your display between the Scan List indicators and trunk bank display, press RVRS . For LTR systems only, the talkgroup must be active in order to change the Scan List and bank indicators. If the talkgroup is not active, change the Scan List by using the Menu screen.
2. Press TRNFR and the smallest empty Scan List appears on the display, then press E . In case you want to change the memory location, you can change it by rotating the VFO . 3. Press RSM to return to Trunk Tracking Search mode. Deleting a Stored ID To delete a stored ID: a.
56 You can hold any I-Call IDs. Because you can only hold on one ID, and there are two IDs involved in any I-Call communication (the transmitting and the receiving units), you might not hear the full conversation, but you probably will.
❖ 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).
58 EDACS ® Reception EDACS ® Tracking TrunkTracker III now allows tracking of EDACS ® trunked systems. Until now these widely used systems have been almost impossible to monitor with a conventional scanner. With your TrunkTracker III listening to EDACS(s) is remarkably easy, and perhaps even easier than conventional scanning.
An EDACS ® T runked system This chart shows how talkgroups are organized within an EDACS system at the Agency level. The individual talkgroups cannot be shown at this scale because there are over 2000. However the chart can show the 16 Agencies in this example.
60 Lists. The powerful AFS Partial Entry feature designed into the BC785D lets you use either a complete talkgroup code, or just the most significant part.
61 EDACS SCA T With the EDACS SCAT feature turned “ ON ” , the data stream transmissions will be eliminated allowing you to clearly monitor the voice communications on EDACS SCAT systems. To monitor EDACS SCAT systems you only need to turn this feature 8:EDCS SCT.
62 LT R ® Reception LT R ® Tracking 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 trunking information as digital subaudible data that accompanies each transmission.
63 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.
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.
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.
66 8. Enter a new Spacing Frequency with the keypad. Note : You can only enter within a range of 5-100 kHz, and 5 or 7.5 or 12.5 kHz multiples. 9. Press E . The display changes for entering the Offset Channel. 10. Enter a new Offset Channel with the keypad.
67 PLAN 1 : Use Plan 1 if the last three digits of ALL the frequencies in use end in one of the following three digits: 125, 375, 625, or 875 (example: 856.1125, 860.7375, 859.6625, 855.8875). PLAN 2 : If the last three digits of frequencies are less than 869.
68 APCO Project 25 Reception APCO Project 25 is a modulation process where voice communications are converted into digital communications. This conversion is similar to the technology used with digital mobile phones. There are several types of Project 25 Systems available! Systems Uniden ’ s BC785D supports are listed below.
4. Replace the cover and tighten the screw. 5. Turn on the scanner, and APCO P25 CARD INSTALLED appears on the display. Installation is completed. You can monitor APCO Project 25 systems. To use P-25 Card, you must program each setting for Conventional mode or Trunking mode.
70 APCO P-25 Sound Quality Fine T uning With each APCO Project 25 system, particularly at 800MHz, the sound quality (C4FM Demodulation Threshold) may need to be fine tuned specifically for that system. If the scanner is not adjusted correctly, the P-25 voice transmissions will sound robotic or unintelligible.
71 4. Once you have adjusted the Sound Quality to the lowest possible level, press the E key. Press the RSM key to exit the Sound Quality Adjustment Mode.
Remote Interface You can communicate and program your BC785D in numerous ways with peripheral devices using the Remote Interface Cable port. This radio offers the following modes: ❖ PC Control mode Program and control your scanner from a PC using Uniden ’ s E-Scanner Software.
