Microphone Gain

The microphone gain of the local headset may need to be adjusted for various audio conditions. The talk/overmodulation (OM) LED should be green if the local headset microphone has been activated. This LED will turn 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 is low, the gain may need to be turned up. The gain should be ad- justed 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.
