switches. The Microphone Mute Switch offers user quick privacy by muting the
microphone pick-up. Slide the switch to position (A) for muting and back to position (B)
to go back to normal speaking mode.The Microphone Gain Switch (C) acts as a
microphone pairing between the headset and your DECT phone. It is not designed to
be a volume control, hence user should only be required to make this setting once.
