3.2.1 How to operate the MCS 221 delegate microphone unit
• For speaking, the microphone of the MCS 221 delegate microphone unit has to be activated. When the micro-
phone is activated, the LED ring of the gooseneck microphone and the LED of the microphone button ቧ will
illuminate. In the “Free” operating mode each delegate can turn on his microphone with the microphone button ቧ.
In the “Request” operating mode, the delegate has to press the microphone button to enter a request-to-speak. In
the “Request” mode the LED ring of the microphone unit will flash, before the chairman can activate the micro-
phone of the delegate microphone unit with the “Req” button. In the “FiFo”mode a microphone unit is turned
off, when another one is turned on. A distance of approx. 30 cm between the speaker and microphone is close
enough.
• When the delegate speaks into his activated microphone, the signal is transmitted via all loudspeakers to the other
microphone units. The loudspeaker of the current speaker is automatically deactivated. Each microphone unit features a
limiter of 40 dB to avoid overrides when talking closely.
Important: If a headphone is connected to the microphone unit, it will be muted when the microphone is activated.
• The microphone of the delegate microphone unit can be turned on voice-controlled, which allows an operation
without pressing the microphone button when the speaker speaks into the microphone.
The “Voice Activation” operating mode can also be selected with the chairman microphone unit.
• The delegate microphone units are turned off, when the delegate presses his microphone button or when the
chairman presses the “Clear” button.
This is also effected with the “Req” button in the “Request” mode, when the next speaker may speak.
In the “Voice” operation the microphone is automatically turned off after a pause of two seconds.
• The admitted talk time for the current speaker can be determined and displayed with the “Timer” function.
Depending on the setting the activated microphone unit can automatically be turned off after an audio warning
for instance or the exceeded talk time is displayed. In addition to standard functions, many settings can be allocated
and changed via configuration switches and programming. This provides a varity of operating modes and operation.
