• If you connect more than 40 microphone units in a chain, you should connect the chairman microphone unit as

first microphone unit to the power supply unit. 

• Press the microphone button 

 to activate the microphone when you want to speak. When you are finished 

with speaking, press the microphone button once again. When the microphone is activated, the LED ring of the
gooseneck and the LED of the microphone button 

 will illuminate. A distance of approx. 30 cm between 

speaker and microphone is close enough.

• In the “Voice Activation” operating mode, you need not press the microphone button. You just speak into the 

microphone. When you are finished with speaking, the microphone is automatically switched off after approx. 
2 seconds.

• To control the meeting, the chairman microphone unit provides control and additional functions, which are explained

in the following chapters: 
– “Free”, “Requ”, “Voice” button, “FiFo” (button combinaton “Free” + “Requ”) to set the operation mode 
– “Prior” button (priority button) for a short interruption e.g. for an announcement 
– “Clear” button to turn off all delegate microphone units simultaneously
