Sensitivity Adjustment
The microphone sensitivity is user-
adjustable by a control which is
accessed through a small hole in the
rear of the housing, using a small flat-
bladed screwdriver. The sensitivity has
been preset at the factory to maximum.
In a noisy environment, it may be
desirable to reduce the sensitivity by
turning the control counterclockwise (as
viewed from the rear of the housing). If
the control is turned completely
counterclockwise, the microphone
output is reduced to zero.
SERVICE
The Desktop Microphone is not
repairable. Order a replacement
microphone as necessary.
