Radio Shack 20-521 owner manual Locking Out IDs, Unlocking a Single ID, Unlocking All IDs

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.

To lock out an ID, press L-OUTwhen the ID appears.

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

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

3.Press L-OUT.

Unlocking All IDs

Note: When you unlock all the IDs, the scan list ap- pears. Press SCAN to scan the IDs stored in your scan lists or press SRC to continue the scanner’s previous function. For more information about scan lists, see “Scan Lists” on Page 48.
