2.2 Setting up
The microphone units have no separate on/off switch. They are switched on and off with the microphone button. By pressing
the button briefly, the microphone unit is switched on. The LED (7) flashes for a moment and the LED (2) on the rear is illuminated. By
pressing the button for more than 2 seconds the microphone unit is switched off and the LED (7) will illuminate twice red/green
briefly. Using the controller software (standby button) the microphone unit can be switched off via the control unit. Furthermore, the
microphone units are switched off automatically, when they do not receive a data signal from the control unit for more than one
minute.
Important:
If the microphone unit is out of range of the MCW-D 100 control unit the LED (7) will flash red. After one minute the microphone unit
will switch off automatically.
Switching on
Switch on the microphone unit by pressing the microphone button briefly. The green operating control LED (2) on the rear will
illuminate.
The microphone units have an integrated rechargeable battery allowing an operating time of at least 10 hours in conference mode.
As soon as the capacity is too low for satisfactory operation, the operating control LED (2) will flash. The remaining time of
operation is around 30 minutes. The decreasing battery voltage is also signaled by the MCW-D 100 control unit at the RS 232 socket
and can be evaluated by an external media control system.
Manual Mode
Press the microphone button (8) to switch the gooseneck microphone on or off.
The LED (7) is illuminated green: The integrated transmitter is adjusted to a free frequency and switched on.
Red ring of the gooseneck
microphone is illuminated: The microphone is ready for talking.
Using the standard version of the MCW-D 100 control unit 3 delegates and 1 chairman can speak simultaneously. Using
additional PCBs inside the MCW-D 100 up to 6 delegates and 1 chairman can speak simultaneously.
Important:
If the number of open microphones is reached, a microphone can only be switched on manually when another
microphone unit has been switched off.
Request-To-Talk Mode
The mode is only possible in conjunction with a PC using the MCW-D Controller software or media control system (AMX/Panja
®
,
Crestron
®
etc.). The request-to-talk is registered in the system by pressing the microphone button of the microphone unit. The allo-
cation is made by the operator at the PC or touchscreen of the media control system. The LED (7) is illuminated to indicate the request-
to-talk. If you press the microphone button again the request-to-talk is cleared. The LED (7) goes out.
2.3 Auto-Off-Function
The delegate microphone units have a power saving auto-off function, i.e. if no-one speaks into the microphone for more than
20 seconds, the microphone unit switches off automatically. The auto-off-function has been deactivated at the factory. The response
threshold and the time after which the microphone switches off can be adjusted with a programming device or PC using the Editor
software. The illuminated ring of the gooseneck microphone will flash 5 seconds before the microphone unit is switched off.
2.4 Addressing the Microphone Units / Serial Number
At the factory each microphone unit is programmed with a different identity number so that the MCW-D 100 control unit can
control them individually. This number is printed on the bottom.
When you subsequently order more microphone units later, please inform the supplier of your current identitiy numbers to avoid
duplication.
