How do I Adjust the Mic Volume on my GN9120/9125/


With the headset turned on (or while on a call), press and release the (+) and (-) buttons simultaneously to change the volume controls to microphone adjustment mode.

Immediately tap the (+) button to increase your volume or the (-) button to lower your microphone volume.

Note: The red light on the headset will start to flash rapidly when it is in the microphone volume adjustment mode. Also, this mode will time itself out after a few seconds of being idle saving the mic volume where you left it.
