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.
