OPERATION

TURNING ON THE SCANNER/SETTING VOLUME AND SQUELCH

1.Turn SQUELCH fully counterclockwise (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 coun- terclockwise. If reception is poor, turn SQUELCH clock- wise 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 coun- terclockwise to OFF.

RESETTING/INITIALIZING THE SCANNER

If the scanner’s display locks up or does not work properly after you connect a power source, you might need to reset or initialize the scanner.

Important: If you have problems, first try to reset the scanner (see “Resetting the Scanner” on Page 26). If that does not work, you can initialize the scanner (see “Initializing the Scanner” on Page 26); however, this clears all information stored in your scanner’s memory.
