3.Turn SQUELCH clockwise, then leave it set to a point just after the hissing sound stops.
Notes:
•If you have not stored frequencies into any channels, the scanner does not scan.
•If the scanner picks up unwanted, partial, or very weak transmis- sions, turn SQUELCH clockwise to decrease the scanner's sensitiv- ity 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 hissing sound, the scanner does not scan properly.
