User Manual

Note: MIC SENS (microphone sensitivity) sets the threshold of sound volume
that the microphone can pick up. The higher it is, the more sound is picked up.
MIC SENS does not affect the talker but affects the other listeners of the
group. It is good practice to lower the setting in a noisy environment so that
other users will not hear so much environment noise.
