Turning The Key Tone On And Off; Using The Keylock - GRE PSR-255 Owner's Manual

TURNING THE KEY TONE ON AND OFF

Each time you press any of the scanner's keys (except (key
symbol) and LIGHT), the scanner sounds a tone.
Follow these steps to turn the scanner's key tone off or back
on.
1. If the scanner is on, turn VOLUME counterclockwise until
it clicks to turn it off.
2. While you hold down the 2 and E keys, turn on the scan-
ner.
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 fea-
ture. When the keypad is locked, the only controls that oper-
ate are LIGHT, VOLUME, and SQUELCH (and the scanner
continues to scan channels).
To turn on the keylock, hold down (key symbol) for about 3
seconds until (key symbol) appears. The scanner beeps
three times (if the key tone is turned on). To turn it off, hold
(key symbol) for about 3 seconds until (key symbol) disap-
pears.
