Adjusting Microphone Gain: If the transmitted audio from the microphone is too
high or too low, remove the belt clip on the rear of the unit and pry out the small
rubber plug to the right of the screw boss. This will reveal the microphone gain
control potentiometer. Using a plastic screwdriver (supplied), adjust the gain con-
trol clockwise to increase the microphone gain or counterclockwise to decrease the
microphone gain. Reinstall the rubber plug and belt clip when adjustments are
complete.

Adjusting Microphone Gain
If the microphone gain is too high, the over modulation LED (the Over Modulation
Circuitry uses the same LED as the Low Battery Circuitry [labeled bat/ ovmod])
will be illuminated when you are talking. Decrease the Microphone Gain until this
illumination ceases when talking in a normal tone.
