Microphone Gain Adjustment
The microphone gain has been factory-adjusted to the nominal level required
for aviation use, 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.
Ear Cushion Replacement
To remove an old ear cushion, simply grasp it and pull it off the earcup. To
install a new ear cushion, start at the top of the earcup. Place the flap on the
back of the ear cushion over the lip along the top of the earcup. Then, pull
the bottom of the ear cushion down over the lip at the bottom of the earcup.
