SPECIAL FEATURES
USING THE KEYLOCK
Once you program your scanner, you can protect it from accidental
program changes by turning on the keylock feature. In this mode, the
only controls that operate are
SCAN , MANUAL , KEYLOCK ( ), VOL-
UME , and SQUELCH .
Note: Turning on the keylock does not prevent the scanner from scan-
ning channels.
To turn the keylock on or off, turn on the scanner then hold down KEY-
LOCK until the scanner beeps and KEYLOCK appears or disappears.
LOCKING OUT CHANNELS
You can increase the effective scanning speed by locking out individual
channels that have a continuous transmission, such as a weather
channel. To lock out a channel, manually select the channel then press
LOCKOUT ( S/S ). L/O appears.
To remove the lockout from a channel, manually select the channel
then press
LOCKOUT . L/O disappears.
Note: You can manually select locked-out channels.
To remove the lockout from all channels, follow these steps:
1. While scanning, turn on the memory banks you want to unlock.
2. Press MANUAL .
3. Hold down LOCKOUT for at least 3 seconds. The scanner beeps
twice, and all locked out memory channels in the selected banks
are unlocked.
