Trunking Operations

For EDACS and LTR systems, you must enter the

NOTES 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 finds 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 fire 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, fire, or NOTE other agencies, refer to frequency guides available at your

local RadioShack store.
