MIC GAIN

ACCESS
Microphone Gain Adjustment
The microphone gain has been factory-adjusted to the nominal level required
for FAA certification, and it should normally not require readjustment. Any
changes to the mic gain should be done by a qualified avionics technician.
To access the gain trimmer, insert a small flat-blade screwdriver through the
access hole in the mic assembly. Clockwise rotation of the trimmer increases
gain.
