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.You can select the type of the
frequency when you turn the unit ON.
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.
