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 BC250D scans the Frequencies you have programmed into the Scanner ’ s channels until it finds an active frequency.
frequency so another talkgroup can use it. Sharing of the available public service frequencies, or trunking, allows cities, counties, or other agencies to accommodate hundreds of users with relatively few frequencies. Following a conversation on a trunked system using a scanner is difficult, if not impossible.
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.
• PC Programmable – Allows you to easily program all frequencies and Trunking Talk Groups into your BC250D through Uniden ’ s E-Scanner software running on your PC. – For more information on E-Scanner Programming software visit our website at scanner.
11 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.

13 Setup Installing the Battery Pack 1. Open the cover. 2. Connect the battery pack connector observing the correct polarity. 3. Replace the cover and press down until it clicks into place. Charging the Battery Pack Use the AC Adapter/Charger to power the BC250D from an AC outlet.
Flexible Antenna Attach the flexible antenna to the antenna connector. Beltclip The beltclip is designed to fit snugly on the back of the scanner. Line up the four arms on the beltclip with the four tabs on the scanner and slide the beltclip into place, as shown on the right.
15 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 begin hearing conversations regularly.
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.
• ID Search mode/ID Search Hold mode Menu Description and Numeric Keypad Equivalents Below are the Menu screens and a brief description or purpose of the feature.
You can program up to 10 search ranges. The first time you program a range you will need to do so through the Menu. After the first time you can program a range as you do on most any other scanner, using the numeric keypad or VFO control. Use this Menu item to select the search range that you want to program.
5:TONE DATA The default mode is 2:OFF . This means that you will receive all transmissions on any frequencies that are active within your search range(s). By selecting CTCSS or DCS you can set the radio to receive only a particular subaudible tone to be received during your search.
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.
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.
can then do the following: 1. Program ID number 2. Set an alpha tag 3. Assign a Beep Alert to the ID. Whenever that ID is active, you will hear three beeps at the start of the transmission. 4:DELAY You can set a delay for a trunk system on a bank by bank basis.
ON. In Search mode, with I-CALL ON, you will hear both talkgroup calls and I-CALLs. You can also set I-CALLs to I-CALL ONLY during which you will monitor only I-CALLs in Search mode.
tone. Only in rare instances will you need to adjust the default settings. The condition to return to control channels depends on whether a signal is present or not.
25 7:DATA SKIP A scanner will normally stop on any transmission it receives. This means the BC250D will occasionally stop on data signals and unmodulated transmissions. You can automatically skip many of these types of transmissions with data skip turned ON.
26 Programming Before the BC250D 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: • To clear a mistake while entering the frequency, press (decimal key) repeatedly until the display is cleared. • If you enter a channel or frequency which is out of the scanner ’ s range, a beep will sound and ERROR appears on the display.
T ransfer Frequencies You can transfer a frequency that has been stored in a channel to another channel. 1. Press HOLD/MAN . 2. Press TRANSFR , 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 3. Select the channel number by rotating the VFO and pressing E . You can also enter the channel number by using the keypad and then press E . 4. Select 1:FREQUENCY and ALPHA TAG by rotating the VFO and pressing E . Note: You can only assign a text tag to the channel where the frequency is stored.
• Group similar services into a bank. For example, program police frequencies in channels 1 through 10 and fire/emergency into channels 51 through 60, and so on. • Put the frequency that you listen to the most or the most important frequency into a Priority channel.
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.
2. Press TRNSFR , and the smallest empty channel number flashes on the display. 3. Press E . Note : • If you want to change the channel, rotate the VFO . • If the frequency you want to store exists already, WARNING appears on the display and you will hear a beep.
1:CONVENTIONAL by rotating the VFO and pressing E . 3. Select the channel number of the stored frequency to be delayed by rotating the VFO and pressing E .
Restoring a Locked-out Channel 1. Press HOLD/MAN . 2. Select a locked out channel. a. Enter the channel number using the keypad. b. Then press HOLD/MAN again. 3. Press L/O to unlock the channel. The L/O icon disappears. Restoring All Locked-out Channels You can restore all locked-out channels in a bank only when a bank is selected for scan.
35 Changing the Priority Channel You cannot eliminate the Priority Channel, but you can change it to any one of the 100 available channels in each bank. 1. Press HOLD/MAN . 2. Select a new Priority Channel: a. Enter the channel number using the keypad.
Searching Setting a Search Range Note : First you must set the search ranges through the Menu screen prior to any searching. The BC250D can search up to 10 separate frequency ranges to help you discover new stations in your area. To set a Search Range, enter into the Menu mode.
Caution: After you have entered the search range while still in the Menu mode, you can set your alpha tag (see page 28), change the step size of the search, change the mode or change the trunk set.
1. Press MENU/BACK . 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 . When Data Skip is active, your scanner may pause momentarily on an unwanted signal but will resume searching in 2 or 3 seconds.
39 2. Press TRNSFR to store the frequency in the channel you selected. The smallest empty channel number flashes on the display. If necessary, you can also change the channel by scrolling the VFO . 3. Press E . Note : • If the frequency you want to store exists already, WARNING appears on the display and you will hear a beep.
6. Press SEARCH to start auto storing. 7. After the search has gone through the search range, press HOLD/MAN to stop this feature. STORE END appears on the display. You may want to let it run through the search range several times because during the first pass there may not have been any transmissions at that particular time on that frequency.
41 3. Rotate the VFO to select one type ( 1:CSQ , 2:TONE SQ , 3:TONE SEARCH ) and press E . 4. To set Tone Lock mode, do the following first, then select 2:TONE SQ in step 3. 1) For Scan mode, select 2:SCAN OPTION / 1:CONVENTIONAL - select the channel number - 3:TONE DATA - 1:CTCSS or 2:DCS by rotating the VFO and pressing E .
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.
commonly used at special events and other locations and may or may not be licensed. • When you rotate the VFO while the Service Search is active, you can change the search direction to up or down. During the search of one of the preprogrammed services, the lowest display line will indicate the service that you are searching.
45 Note : You can also set Alert mode to OFF by pressing RSM without entering the Menu mode. 4. When the unit receives a warning signal, it shows a message with the alert siren defined. (For NWR-SAME EVENT CODE, see the table on page 99.) 5. To deactivate, just press any key or it is automatically canceled and the alert siren stops.
46 When you rotate the VFO to move down when FIPS CODE 1 is displayed or VFO to move up when FIPS CODE 15 is displayed, ALL FIPS appears on the display. 5. Enter the FIPS code using the keypad. 6. Press E . Note : • To cancel the entry, press (decimal key).
Digital and T runked Systems Your BC250D is designed to monitor APCO Project 25 digital communication systems (using optional BCi25D) and tracks three major types of trunked radio systems.
Safety Trunked System Frequency Guide included with your BC250D scanner. Frequencies sometimes change, check with www.bearcat1.com/free.htm . • If you have internet access, you can visit scanner.uniden.com or www.bearcat1.com/free.htm for additional information, for current news and frequency information, about Trunk Tracking Scanning.
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.
71 for instructions. STEP 1 is complete. Note: Information on APCO P-25 Systems are referred to in “ APCO Project 25 Reception ” on page 76. 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.
press (decimal key) twice, and the display is cleared. • If you enter a frequency which is out of the system ’ s trunking range, a beep sounds and ERROR appears on the display.
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. (The first number represents the Scan List number and the second number represents the Memory Location number.
To enter a LTR ID: For a LTR ID, the Area Code, Home Repeat number and ID make up the talk group ID. Please see page 68 for more information. 1. Enter the Area Code and then press (decimal key) 2. Enter the Home Repeater number and then press (decimal key).
Setting the Squelch For trunked reception, a good setting for the SQUELCH control is in the center of the range with the color marker pointing up. See the illustration. If it is set too high (CCW) in some cases it could prevent your scanner from locking to the Control Channel reliably.
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. 2. To remove a Scan List from active scanning, press the number of the Scan List on your keypad. Hint: Press and hold RSM for 2 seconds, the scanner will move to the next trunking bank.
ID Scan Hold Feature If you want to stop on a ID during ID scanning, press HOLD/MAN . If you want to resume scanning, press RSM . To directly access a specific channel: There are several ways to access a specific ID quickly. 1. Press HOLD/MAN . 2. By using the keypad or rotating the VFO , enter the ID location number (See page 51).
selected for a trunked system, press HOLD/MAN , and the radio will seek and acquire the trunked system control channel. ID Search Hold and Direct Entry ID Hold Mode Just like in Conventional Search, Hold lets you pause ID Search on an interesting transmission without storing the talkgroup into memory.
talkgroups in the Utilities agency. You can do this with just a few key presses. To use ID BLOCKOUT just enter the Agency- part, or the Agency-Fleet part, of the talkgroup code and press L/O . For example, to Blockout Agency 4 in Trunk Search, press HOLD/MAN , 0 , 4 , (decimal key), and then L/O .
Reverse Key For Motorola and EDACS system; to change your display between the Scan List indicators and trunk bank display, press REVERSE . 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.
Setting Priority in T runking Mode You can set priority in your trunking lists, just as you do in your conventional ones. You can set the priority by pressing and holding PRI for 2 seconds in ID Scan Hold mode. After you ’ ve set up your Scan List, press PRI to activate it.
61 Moving between Scan List Memories There are a number of ways to step and move through your Scan List memories: 1. Press HOLD/MAN in the ID Scan mode and rotate the VFO to move to up or down. 2. Or, press HOLD/MAN in the ID Scan mode, next press 0-9 (scan list number), then press 0-9 (memory position).
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.
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 .
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.
65 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.
66 For example Sullivan, in decimal, uses channels from 384 to 511. This is not as easy to remember as Agency 03. But decimal is useful if you need to work from decimal talkgroup lists.
EDACS systems often provide users with an 'Emergency' mode on their radios. Users in trouble can alert the dispatcher and other units and get priority access to the radio system. When a user activates Emergency mode, EMERGENCY will flash the display during the entire transmission.
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.
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.
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.
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.
Setting the Base, Spacing Frequencies and Offset Channel for Motorola VHF/UHF T runked 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.
73 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.
PLAN 2 : If the last three digits of frequencies are less than 869.0000 and end in one of the following three digits (125, 375, 625, or 875) and if ANY other frequencies end in (000, 250, 500, or 750) use Plan 2.
75 Disconnect T one Detect Option (End Code) When this function is disabled, the radio looks for squelch before returning to the Control Channel instead of waiting for the Disconnect Tone. Only in rare instances will you need to adjust the default settings.
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 the Uniden BC250D supports are listed below.
77 5. Replace the cover and press down until it clicks into place, and then turn ON the scanner. APCO P25 CARD INSTALLED appears on the display. Installation is complete. You can monitor APCO Project 25 systems. To use the P-25 card, you must program each channel for Conventional mode or Trunking mode.
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.
79 assigned theoretically, and the values are not to guarantee the operation of the unit. • The M id threshold value will not change while adjusting the upper and lower limits. 4. Once you have adjusted the Sound Quality to the lowest possible level, press the E key.
80 Remote Interface You can communicate and program your BC250D 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.
81 Start Remote Mode and Change Transfer Speed: Through the Menu system, select 3:SYSTEM OPTION / 5:PC CONTROL by rotating the VFO and pressing E . To start Remote mode, choose from the transfer speed list except for 5:OFF .
82 To connect the Scanner to Scanner: Plug the smaller end of each of the supplied Remote Interface Cables into the remote ports in accordance with the direction of the marks which are on the right sides of each of the two scanners.
83 6. Press SCAN on both scanners. The data transfer begins from the Master Unit to the Slave Unit. During the data transfer, both scanners show the following displays. When the data transfer is complete, COMPLETE displays. If the data transfer is not successful, the following error message will appear.
84 Additional Features The following additional features are designed for you to customize your scanner. Once these features have been turned ON or OFF, they will remain as they are set until you reset them, even if you turn the scanner OFF and then ON again.
85 Key Beep Option To choose key beep sound 1:ON or 2:OFF : 1. Press MENU/BACK . 2. Select 3:SYSTEM OPTION / 3:KEY BEEP by rotating the VFO and pressing E .
86 You will not hear any audio. This feature does not function in the WX Alert mode, because the audio is already muted. To turn it OFF, press and hold MUTE again. Receiving Mode Selection You can also set the receiving mode, AM or FM etc., in Conventional mode or Chain Search mode.
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.
88 T roubleshooting If your BC250D 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 .
