BASIC OPERATION
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 remain open and you should
have a better chance of hearing weak signals.
To return to normal operation, press the MONITOR key momentarily.
ANL (Automatic Noise Limiter) Feature
For reduction of impulse noise, such as that produced by an engine’s ignition system, the ANL feature may prove helpful.
r To activate the ANL fea-
ture, press the 
key m o m e n t a r i l y. T h e “ANL” icon will appear on the display, and you should observe a reduction in the ignition noise.
rTo turn the ANL feature off, press the 
key again; the “ANL” icon will disappear from the display.
