Searching for Talk Group IDs
If you tune the scanner to an active Motorola
control channel, the Motorola System ID and
the approximate control channel message
decode success rate appears. This helps you
identify the system and the reception quality.
When the scanner decodes control channel data
from a Motorola system, COTRL appears on the
display.
To search for Talk Group IDs:
1. Set the bank to Open mode.
2. Press SCAN. The scanner scans through all
unlocked channels in the active banks.
3. When the scanner stops on a transmission,
press TRUNK. The scanner displays the ID
location:
Sub-bank. ID Location
0-4 00-29
Example: 2-01
If the ID has already been saved, “ID was
saved” appears.
If you try to store more than 150 talk
group IDs in a bank, “Memory Full!”
appears.
Saving a Talk Group ID
Each of the 10 banks contains 5 sub-banks that
each hold 30 Talk Group IDs. (You can save up
to 1,500 Talk Group IDs.) When the scanner
receives a trunked transmission, it searches
the associated sub-bank for the Talk Group
ID to decode data for Motorola, EDACS (GE/
Ericsson), and LTR (EF Johnson) systems.
To dene a Talk Group ID:
1. Press PGM, then press TRUNK to enter the
ID program mode.
2. Press FUNC, then use or to select a
bank.
3. Repeatedly press MODE to select a trunking
mode (Motorola, EDACS, or LTR).
4. Repeatedly press TRUNK to select the sub-
bank.
5. Press or to select the location where to
store the Talk Group ID.
6. Use the number and decimal point keys to
enter the Talk Group ID:
For ED Talk Group IDs, you can enter either
a decimal or AFS code. The default setting
is decimal ID entry.
To use the AFS code, press FUNC then 2,
“AFS Format” appears for about 2 seconds.
You can then enter the AFS code.
If you make a mistake, “Invalid ID value”
appears when you press ENT. Go back to
Step 3.
If you entered an ID that is already stored
in same bank, “Dupl. ID of X-XX appears.”
To store the ID code, press ENT. To cancel,
press CL.
7. Press ENT.
