Basic Operation

Turn the Scanner On

Turn the VOLUME 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 begin hearing conversations regularly.

Note: If you turn the scanner on when the optional APCO card is not installed, APCO P25 CARD NOT INSTALLED appears on the display. To delete the message, select 2:DISABLE in the Menu mode (see page 77).

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/MAN until you do not hear a signal.

2.Make sure that the VOLUME 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.
