Uniden Bc250d Widenband Scanner Owners Manual

Digital and Trunked
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. These systems
are described here.
❖APCO Project 25 Systems - Digital systems which support
the APCO  Project 25 protocol developed by the
Telecommunications Industry Association (TIA) and
Electronic Industries Alliance (EIA). Systems can
operate in conventional, trunked (3600) and mixed-
modes (analog and digital) in...

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...

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 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...

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
ERRORappears on the display.
•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 Frequency Alert” on page 27).
STEP 2 is complete.

4. Select 3:TALK  GROUPby rotating the VFOand
pressing E.
5. Select the ID location by rotating the VFOor 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.) (Direct entry
method example: enter 1-5 by
pressing 1, (decimal key), 5.)
6. Select 1:IDby rotating the VFO
and pressing E.
7. Enter the ID. 
Note: After you have programmed the ID in a...

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).
3. Enter the ID you want to store.
4. Press E.
Note: To clear a stored ID while entering an ID, press 0and
Esuccessively, and start over.

Setting the Squelch
For trunked reception, a good setting for
the SQUELCHcontrol 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. If it is set
too low (CW) it will slightly delay finding the Control Channel.
The best setting is the same as for conventional reception,
and is not critical.

ID Scan Mode
1. Press SCANto begin scanning the
lists you have programmed.
If you havent programmed more than
2 IDs, ERRORappears 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 RSMfor 2 seconds, the scanner will
move to the next trunking bank.
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...

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).
3. Press HOLD/MANagain.
Trunked Search
Once you have programmed all the frequencies for a trunked
system, Search will let you immediately start hearing
transmissions.
