TURNING THE KEY TONE ON AND OFF
Each time you press any of the scanner’s keys (except 
and LIGHT), the scanner sounds a tone.
Follow these steps to turn the scanner’s key tone off or back on.

2.While you hold down the 2 and E keys, turn on the scanner.
3.After 1 second, release 2 and E.
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, VOLUME, and SQUELCH (and the scanner continues to scan channels).
To turn on the keylock, hold down 
for about 3 sec-
onds until 
appears. The scanner beeps three times (if
the key tone is turned on). To turn it off, hold down 
for
about 3 seconds until 
disappears.
