SPECIAL FEATURES
USING THE KEYLOCK
Once you program your scanner, you can protect it from
accidental program changes by turning on the keylock
feature. When the keypad is locked, the only controls that
operate are
LIGHT (see “Using the Display Backlight” on
Page 34), VOLUME , and SQUELCH .
Note: The keylock does not prevent the scanner from
scanning channels or monitoring a single channel, which-
ever feature you last selected.
To turn on the keylock, press and hold for about 3
seconds until appears on the display. To turn it off,
press and hold for about 3 seconds until disap-
pears from the display.
LOCKING OUT CHANNELS
You can increase the effective scanning speed by locking
out individual channels that have a continuous transmis-
sion, such as a weather channel (see “National Weather
Frequencies” on Page 36) or birdie frequency (see “Birdie
Frequencies” on Page 37). To lock out a channel, select
that channel then press
E/L-OUT . L/O appears on the dis-
play.
