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
Hold down L/O until you hear two short beeps. Then
press E to unlock all the IDs at once.- The scanner beeps
twice.
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.
