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. The Electronic Communications Privacy Act of 1986, as amended, makes it a federal crime to intentionally intercept cellular or cordless telephone transmissions or to market this radio when alt[...]

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. Scanning stops on an active frequency and remains on that channel as long as the transmission con[...]

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. Because when there's a short brea[...]

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. • Multi-Track – Track more than one tru[...]

• 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.uniden.com . • Turbo Search – Increases the search speed to 300 steps per second. This [...]

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. To obtain frequency information for your area, contact one of the following: • Bearcat Freque[...]

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. Listening Safely To protect your hearing, follow these guidelines when yo[...]

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. Later in a section called "Additional Features", you will find explanations on how to disable the keypad acknowledgement t[...]

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. You can program range 1 through 10, one[...]

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. You can also lockout a particular CTCSS or DCS tone. You may wish t[...]

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 sub[...]

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. 2:TRUNK Choose the Tru[...]

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. ☞ In Search mode, when you hear an interesting I-Call, you can enter the instant shortcut (decimal key) then RSM t[...]

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[...]

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. EDACS systems use &apo[...]

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. The system is logical and easy to understand. EDACS systems are typically arranged i[...]

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. At the beginning of each transmission it will sound a dist[...]

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. Users on an LTR syst[...]

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 ra[...]

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 M[...]

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 tr[...]

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. To find these out, check the scanner.uniden.com or www.bearcat1.com/free.htm and other web sites [...]

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.
