locking out channels

You can lock out reception of any channel so it is not scanned during normal scanning. You can also restore the channel to scanning whenever you wish.

Like conventional scanning, you can lock out reception of unwanted traffic. You can lock out up to 100 IDs. Press L/O on the ID you want to lock out.

To restore all locked out IDs, hold down L/O for 2 seconds or change the state code. If you find an interesting ID you want to continue listening to, press HOLD/RESUME. Press HOLD/ RESUME to resume scanning.
