Power/
Volume/
Squelch
Knob
The
Power/Volume/Squelch
knob located in the bottom left corner of
the bezel controls audio volume for the COM radio. Rotating the knob
clockwise past the detent turns power on and counter-clockwise turns
power off. When the COM radio is active, press the
Power/Volume/
Squelch
knob to toggle automatic squelch control On/Off for the COM
radio.
The GTR 200/200B radio receiver features an automatic squelch that rejects
many localized noise sources. You may override the squelch function by
pressing the
Power/Volume/Squelch
knob. This facilitates listening to a
distant station or setting the desired volume level.
To override the radio receiver automatic squelch, press the
Power/Volume/
Squelch
knob momentarily. Press the
Power/Volume/Squelch
knob again
to return to automatic squelch operation. A “SQ” indication appears to the
left of the active COM frequency window in the upper left corner of the
display when automatic squelch is overridden.
