Basic Operation

Turn the Scanner On

Turn the VOL control clockwise out of the detent position. The scanner automatically starts scanning. Since there are no frequencies programmed in your scanner initially, you may not receive any signals. Once you set the squelch and program some frequencies, you will be hearing conversations regularly.

Setting the Squelch

To set the squelch, you must be in the hold mode, and you should not be receiving a signal on your scanner.

1.Press ▲/HOLD until you do not hear a signal.

2.Make sure that the VOL is set to a comfortable listening level.

3.Think of the Squelch Control as a gate.

Turn the SQUELCH control fully counter-clockwise.

This raises the "Squelch Gate" so high that only very strong signals can get through.

4.Turn SQUELCH clockwise until you hear a hiss. This lowers the "Squelch Gate" so that everything gets through – noise, weak signals, medium signals and strong signals.

5.Turn SQUELCH back counter-clockwise just until the hiss stops. Now the "Squelch Gate" allows only clear signals through.
