Trunking Operations
For EDACS and LTR systems, you must enter the
frequencies in logical channel number (LCN) order.
If you try to enter a duplicate frequency in a bank, the
scanner beeps and the channel which was previously
stored appears.
6. Press or to select the next channel in the bank and repeat
Step 4 to enter frequencies in that bank.
7. Press SRCH to begin searching for the trunk’s data channel
and scan conventional frequencies at the same time. After the
data channel is acquired, the scanner begins a trunk search that
nds all active talk groups in the trunked system.
8. (Optional) To turn a bank on or off, press and hold the SCAN/
MANUAL button during trunk scanning. When the trunked bank
appears, press the bank number (0–9).
talk group ID
Each trunk scanning bank contains ten talk group ID lists (with up to
10 talk group IDs each), for a total of 100 talk group IDs each. These
lists organize trunking system users into categories. For example,
you might use List 1 for police IDs, List 2 for re department IDs,
and List 3 for emergency medical service IDs. After you store talk
group IDs in a list, you can scan them just as you scan conventional
channels.
To locate talk group ID lists for your local police, re, or
other agencies, refer to frequency guides available at your
local RadioShack store.
