Monitor Key; Anl (Automatic Noise Limiter) Feature - Vertex Standard Spirit VXA-700 Operating Manual

Monitor Key

When listening to a very weak signal from an aircraft or
ground station, you may observe the signal disappearing
periodically as the incoming signal strength becomes too
weak to override the squelch threshold setting.
To disable the squelch temporarily, press and hold the
MONITOR key for 2 sec-
onds on the left side of the
radio, just below the PTT
button. The squelch will re-
main open and you should
have a better chance of hear-
ing weak signals.
To return to normal operation, press the MONITOR key
momentarily.
