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 be hearing conversations regularly.
Setting the Squelch
To set the squelch, you must be in the Manual mode, and you
should not be receiving a signal on your scanner.
1. Press 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
SQUELCH fully counter-clockwise. This raises
the “Squelch Gate” so high that only very
strong signals can get through.
4. Turn SQUELCH fully clockwise until you hear
a hiss. This lowers the “Squelch Gate” so that
everything gets through – noise, weak signals,
and strong signals.
5. Turn SQUELCH back counter-clockwise just
until the hiss stops. Now the “Squelch Gate”
allows only clear signals through.
Next you must program some frequencies. (Page 18) It is recommended that you read the
next part “Understanding the Menu System” because it will assist you in accessing and
understanding many of the features. Later in a section called “Additional Features”, you will
find explanations on how to disable the keypad acknowledgement tones, how to mute the
audio, how to change the appearance of the display and other general features.
