ˆOperation

TURNING ON THE SCANNER AND SETTING SQUELCH

1.Turn SQUELCH fully counterclockwise until the indi- cator points to MIN before you turn on the scanner.

2.To turn on the scanner, turn VOLUME clockwise.

3<C:FD<ý0Fý L8Cý0ILEB@E> appears. After about 3

seconds, you hear a hissing sound.

3.Turn SQUELCH clockwise until the hissing sound stops.

4.To turn off the scanner, turn VOLUME counterclock- wise to OFF.

Notes:

•The scanner does not scan if there are no frequen- cies stored in channels. If the scanner does not scan and you have already stored frequencies in channels, turn SQUELCH further clockwise.

•If the scanner picks up unwanted, partial, or very weak transmissions, turn SQUELCH clockwise to decrease the scanner's sensitivity to these signals. If you want to listen to a weak or distant station, turn SQUELCH counterclockwise.

•If SQUELCH is adjusted so you always hear a hiss- ing sound, the scanner will not scan properly.

•To ensure the scanner operates properly while in the trunking mode, we suggest you set SQUELCH using the steps listed above.
