Turning on the Scanner
The squelch and attenuator control scanner
sensitivity. If squelch is set too low, the scanner may
stop on noise or silence.
Note:
Make sure the scanner’s antenna is connected
before you turn it on.
1.
Turn the
SQUELCH
knob
to about mid-position.
2.
Turn the

knob to turn on the radio.
3.
Turn
SQUELCH
down (counterclockwise) until
you hear noise.
4.
Turn

the noise stops. The higher the squelch is set,
the stronger the signal required to break the
squelch.
