TURNING ON THE SCANNER AND SETTING SQUELCH

1.Turn SQUELCH and VOLUME fully counterclockwise.

2.Turn VOLUME back clockwise until you hear a hissing sound.

3.Turn SQUELCH clockwise, then leave it set to a point just after the hissing sound stops.

Notes:

•If the scanner does not scan, turn SQUELCH further clockwise.

•If the scanner picks up unwanted, partial, or very weak transmis- sions, turn SQUELCH clockwise to decrease the scanner’s sensitivity to these signals. If you want to lis- ten to a weak or distant station, turn SQUELCH counterclockwise.

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