Monitor Key
When listening to a very weak signal from an air-
craft 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 seconds on the left
side of the radio, just be-
low the
PTT
button. The
squelch will remain
open and you should have a better chance of hearing
weak signals.
To return to normal operation, press the
MONITOR
key momentarily.
