Loudspeakers or Headset?
Your system comes with built-in loudspeakers and microphones. In addition you may connect a headset, with or
without microphone, to the system. Once you connect a headset and/or a microphone to the system, this will be
detected automatically.

Mic Off
To mute the microphone during a call, press the Mic Off button. An on-screen
indicator appears in the upper right corner when the microphone is OFF. In a
call, if audio is detected, the on-screen symbol will start to flash. Pressing the
Mic Off button one more time will activate the microphone again.
Note! Mic Off will mute all microphone inputs, but it will not mute audio from
any AUX and VCR inputs.
When an incoming call is answered, the microphone may be in the off state
because the Auto Answer setting is On+Mic Off, see Control Panel > Auto
Answer. The icon will flash once you start speaking. Remember to turn on the
microphone before a meeting.

Using the Internal / Headset Switch
There are connectors for the headset and the headset-microphone
on the left side of the socket, when viewed from the front – see Fig.
The little switch is used to toggle between the system’s own
speakers/microphone and the headset’s.
If you connect headset only (no microphone) the toggling will be
between the systems’s loudspeakers and the headset’s.
If you connect headset and mic., the toggling will be between the system’s
speakers/microphone and the headset’s.
If you connect a microphone only (no headset), nothing will happen
when you press the switch.
