4.5 Volume Adjustment

You can easily adjust the volume by tapping the (+) Button or the (-)
Button. The volume is set and maintained independently at different
levels for each audio source even when you reboot the headset. For
example, once you set the volume for mobile phone handsfree, it will
not change even if you adjust the volume for your Bluetooth MP3
music. However, if you adjust the volume during stand-by mode, it will
affect volume levels of every audio source.

4.6 Muting the Microphone

To mute or unmute the microphone, press and hold the Center Button
and the (-) Button for 1 second. When the microphone is muted, you
will hear ascending beeps every 10 seconds. When you unmute the
microphone, you will hear descending beeps and the microphone will
be active.
