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 tem-
porarily, press and hold the
MONITOR
key for 2 sec-
onds on the left side of the
radio, just below the
PTT
button. The “ ” icon will
appear on the display, and
the squelch will remain open
and you should have a better
chance of hearing weak sig-
nals.
To return to normal operation, press the
MONITOR
key
momentarily; the “ ” icon will disappear from the dis-
play.
