Base Station Microphone Gain Adjustment
The microphone gain adjustment allows you to adjust the level of your voice
as it is transmitted from the headsets plugged into the base station, to the
rest of the system.
Microphone gain must be adjusted for each base station headset.
1
Use a headset that is plugged into the right side of a base station, and
locate the MIC GAIN adjustment that is recessed in a hole on the right
side of the base station.
2
Insert a small screwdriver in the
hole and turn the adjustment
clockwise to increase or
counterclockwise to decrease
microphone gain.
3
Speak into the headset microphone and listen to your own voice level
(sidetone) in the headset as you adjust the microphone gain.
4
Use a headset that is plugged into the left side of a base station, and
locate the MIC GAIN adjustment on the left side of the base station, and
then repeat steps 2 and 3 for the left side headset.
5
Repeat steps 1 through 4 for each base station.
NOTE: Base station microphone gain is factory set at about one-third from minimum level.
