3.3.1 How to operate the MCS 223 chairman microphone unit
• 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 ቦ 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 ቦ 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
