Searching for Locked Out Channels
In Scan Mode, you will not see locked out channels. However,
to search for locked out channels and display them on the
screen, use [UP] and [DOWN]. These keys will enable you to
search manually through the bank in Hold Mode only. "L/O"
will appear on the screen to indicate the locked out channel.
Restoring a Locked Out Channel
Suppose you want to unlock Channel 12 of the PRIVATE
bank. Press [PRIVATE] to start scanning. Press [HOLD] to
stop scanning. ("HOLD" & "SCAN" must appear on the
screen.) Use [UP] or [DOWN] to find locked out Channel 12
(which shows "L/O"). Then press [L/O]. "L/O" disappears to
indicate that Channel 12 is now unlocked and restored for
scanning.
Note: For the factory pre-programmed channels, the earliest
channel will be unlocked, when you lock out more than 20,
30, 40 or all channels.
Restoring All Locked Out Channels
1. You can unlock all locked out channels in any bank at one
time. Press a bank key to start scanning.
2. Press [HOLD] to stop scanning.
3. Press and hold down [L/O] ("L/O" appears on the screen)
for more than 2.5 seconds until you hear the multi-beep
("L/O" disappears).
Now all locked out channels in the bank are unlocked and
restored for scanning.
