Battery Check
As you rotate the OFF/ON volume control knob clockwise to turn the unit on, note that the battery LED (Labeled “BAT/O.M.”) should flash one time on good batteries. Poor batteries will cause the LED to be illuminated continuously and a bad or unus- able battery will not cause any illumination at all.

Microphone Gain
The microphone gain of the beltpack’s headset may need to be adjusted for various audio conditions. The Battery/Overmodulation (O.M.) LED will flash red when Mic Gain is too high and will need to be turned down. If the LED does not flash red at all, and the audio from the unit sounds low, then the gain may need to be turned up. The gain should be adjusted so the LED flashes red only on loudest speech.
Using the plastic screwdriver (supplied), adjust the control appropriately. Note that the volume heard can also be adjusted by changing the spacing be- tween the microphone and your mouth.
