The LED (7) flashes for a moment and the LED (2) on the rear is illuminated. Bypressing the button for more than 2 seconds the microphone unit is switched off and the LED (7) will illuminate twice red/greenbriefly. Using the controller software (standby button) the microphone unit can be switched off via the control unit. Furthermore, themicrophone units are switched off automatically, when they do not receive a data signal from the control unit for more than oneminute.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 unitwill switch off automatically.Switching onSwitch 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 socketand can be evaluated by an external media control system.Manual ModePress 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 gooseneckmicrophone 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 ModeThe 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-FunctionThe delegate microphone units have a power saving auto-off function, i.e. if no-one speaks into the microphone for more than20 seconds, the microphone unit switches off automatically. The auto-off-function has been deactivated at the factory. The responsethreshold and the time after which the microphone switches off can be adjusted with a programming device or PC using the Editorsoftware. 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 NumberAt the factory each microphone unit is programmed with a different identity number so that the MCW-D 100 control unit cancontrol 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.
202.5 Documentation OutputA headphone (e.g. DT 301) can be connected to the documentation output (4). We recommend a min. impedance of 200 Ω.ATTENTION: This connection has been covered, because at present special headphones can be connected only. If you needthis connection please contact beyerdynamic.2.6 CA 2455 External Power SupplyThe MCW-D microphone units can be powered with the CA 2455 external power supply unit which can be connected to themulti-function socket (1). The DC-voltage should be 18 V DC (±0.5 V), current max. 180 mA, residual hum < 20 mV.Important:Connect and disconnect the external power supply only when the microphone unit is switched off. If the microphone unit is powered by the DC-power supply first and when the power supply is switched off, the microphone unit will bepowered by the integrated battery until it is nearly empty. The microphone unit switches off automatically to avoid an exhaustive discharge.But if the switched on microphone unit is powered by the battery first and then connected to DC-power, the external power supply willpower the microphone unit.2.7 Maintenance of the MCW-D Microphone UnitsFor cleaning the MCW-D microphone units when they are slightly dirty (finger prints, dust, jam or juice) use a soft, damp cloth,sponge or brush and a liquid cleaning agent. Before cleaning the surface it must be moistened thoroughly. Afterwards it must becleaned with clear water. Make sure not to allow any water to enter the unit. For dirt caused by mineral oils and fats, animal andvegetable fats use spirit, isopropyl alcohol or benzine.For dirt caused by ballpoint pens, typewriter ribbons or carbon paper use isopropyl alcohol or spirit.Clean the supplied pop shield with clear water. Make sure that it is completely dry before you put it on the microphone again.2.8 Safety CodeUsing the MCW-D Editor software or the MCW-D 1003 programming device a safety code can be entered for the MCW-D micro-phone units and the MCW-D 100 control unit within one system. This will increase the safety against unauthorised listening. For adetailed description please refer to the appropriate manuals.
