Locking Out IDs

As with conventional scanning, it is possible to lock out unwanted traffic. This is particularly important in trunked systems because signals you cannot listen to (such as water meters, door alarms, traffic signals, and encrypted signals) are assigned IDs just like other users. You can have up to 100 IDs locked out at one time.

Note: If you lock out an ID while searching, it is also locked out of the scan list(s). See “Scan Lists” on Page 41.

To lock out an ID, press L/O when the ID appears.

The ID is locked out, and the next active ID appears.

Unlocking a Single ID

1.Hold down L/O until you hear two short beeps.

2.Repeatedly press t or s to select the ID you want to unlock.

3.Press L/O.

The ID is unlocked and the next locked ID or –

– –––(if there are no other locked IDs) appears.

4.Press SRCH to continue the scanner’s previous func- tion.

Unlocking All IDs

Note: When you unlock all the IDs, the scan list mode appears. Press SCAN to scan the IDs stored in your scan lists or press SRCH to continue the scanner’s previous function. For more information about scan lists, see “Scan Lists” on Page 41.
