this may result with either muting the speaker or microphone unexpectedly, or
worse may damage the controller itself.
If you are unsure of whether you have accidentally activated any mute function, always
check the LED-indicator to make sure. For details to the various LED-status, please
refer back to p.6 of this manual.
