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.
Note
:
If you turn the Scanner on when the optional APCO Cord 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 69).
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
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.
