Squelch Control
Squelch is controlled by turning the lower rotary
concentric knob located directly below the
On/Off/Volume switch.
With the power On, turn the knob
counterclockwise until you hear a hissing sound,
then turn the knob clockwise until the hissing
stops. This will establish a “Baseline” squelch. By
turning the knob further in a clockwise direction,
you will filter weak and medium-strength signals.
By turning the knob in a counterclockwise
direction (further from your baseline setting), you
will receive weaker signals. Squelch Control filters
weak signals and radio frequency (RF) noise so
that you will clearly hear the signals you want.
NOTE
If the Squelch is set so that you can hear a
continuous hissing sound, the Memory Scan
and Tri-Watch functions will be blocked.
Radio Speaker and Microphone
The internal Radio Speaker and Microphone are
located on the bottom front face of the radio below the
lower control buttons.
An optional Speaker/Microphone port is located at the
top of the radio between the antenna and the
Power/Volume/Squelch control. Unthread the
Speaker/Microphone port cover to access and install
an optional speaker or microphone into this port.
