Operating the chairperson unit

On the chairperson unit, all three keys (MIC, P1 and P2) are assigned

functions.

The MIC key

In addition to the six language channels, the SDC conference system

features a chairperson channel via which the chairperson can join in a

discussion without limitations.

 Press the MIC key . The signal light ring  and the LED  on your

console light up and you can take the floor immediately.

If you have finished speaking, press the MIC key  once more. The signal

light ring  and the LED  on your console go off.

If a conference has more than one chairperson, and if the chairperson

channel is already used by one of the chairpersons, the units of the other

chairpersons function like normal delegate units (see “Making a request

to speak” on page 68).

The P1 key

In “Automatic” and “Overrun” mode:

With the P1 key , the chairperson can interrupt a discussion any time

(priority). By pressing the P1 key , all other active microphones are

turned off and the chairperson can take the floor immediately. The signal

light ring  and the LED  on the chairperson unit light up while the

signal light ring  and the LED  on the deactivated delegate units start

flashing.

By pressing the P1 key  once more, the previously deactivated

microphones are turned on again. The signal light ring  and the LED 

on the chairperson unit go off while the signal light ring  and the LED 

on the re-activated units light up permanently.

In “Request” mode:

By pressing the P1 key , the chairperson turns off the microphone of the

first speaker in the discussion group and activates the microphone of the

first participant from the request-to-speak list.
