5.2 How to operate the chairman microphone unit
The chairman can turn on his microphone unit via the microphone button at any time independent of the selected
limit. The chairman unit provides two additional buttons to conduct a meeting actively: “Prior” and “Clear”.
“Prior” button
The “Prior” button operates only, if the microphone station has been programmed as a chairman station via the
MCS-D 200.
For a brief interruption or announcement the “Prior” button must be held down. If the microphone was turned off,
it will be turned on by pressing the “Prior” button. All the other activated microphones remain muted while the LED
of the microphone button is flashing, until the “Prior” button is released.
By using the “Prior” button, chairmen of a higher level can mute the microphones of all delegate units as well as the
microphones of all chairman units of a lower level.
“Clear” button
The “Clear” button operates only, if the microphone unit has been programmed as a chairman unit via the
MCS-D 200.
• Touch the “clear” button briefly (< 1s):
The microphones of all speakers are deactivated simultaneously; requests to speak are not cleared.
• Hold down the “clear” button (> 1s):
The microphones of all speakers are deactivated simultaneously; requests to speak are cleared.
This applies for all operating modes.
5.3 How to adjust the headphone volume
Use the Vol +/- button to adjust the volume of the headphone connected to the operating panel.
The settings remain stored even when the system is turned off.
5.4 How to select the language or channel
Use the CH +/- button to select the available language channel, original channel (OR) or another information, audio
or music channel, which is then transmitted via the headphone connected.
Channels are created via the MCS-D 200 control unit or the iCNS software.
The settings remain stored even when the system is turned off.

the guarantee.
