OPERATION
TURNING ON THE SCANNER/SETTING VOLUME AND
SQUELCH
1. Turn SQUELCH until the indicator points to MIN before you turn on the scanner.
2. To turn on the scanner, turn VOLUME clockwise until you hear a hissing sound.
3. Turn SQUELCH clockwise, just until the hissing sound stops.
Notes:
• To listen to a weak or distant station, turn SQUELCH counterclockwise. If reception is poor,
turn SQUELCH clockwise to cut out weak transmissions.
• If SQUELCH is adjusted so you always hear a hissing sound, the scanner will not scan or
search properly.
4. To turn off the scanner when you finish, turn
VOLUME counterclockwise to OFF.
STORING KNOWN FREQUENCIES INTO CHANNELS
Good references for active frequencies are the RadioShack Police Call Guide including
Fire and Emergency Services, Official Aeronautical Frequency Directory, and Maritime
Frequency Directory. We update these directories every year, so be sure to get a current
copy.
