Locking Out IDs

As with conventional scanning, it is possible to lock out unwanted traffic. This is particularly important in trunk- ed systems because signals you cannot listen to (such as water meters, door alarms, traffic signals, and en- crypted 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 48.

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