4. Delegate and Chairman Microphone Units
• At the factory each microphone unit is programmed with a different serial number so that the MCW-D 50 control unit can control them.
The serial number is printed on the bottom of each microphone unit.
• Via radio communication each microphone unit is addressed in the transmission protocol via an individual ID number. This ID number can
be changed with the MCW-D 50 Conference Software. On delivery the ID number corresponds to the last four digits of the serial number.
• When you order more microphone units later, please inform the supplier of the configuration of the control unit and the identity / serial
numbers of the microphone units.
4.1 MCW-D 521 / 523 and MCW-D 531 / 533 Microphone Units
4.1.1 Controls and Indicators
Important:
• The charging contacts of the microphone units can cause damages, injuries or fire damages if they come into contact with
conductive materials such as jewellery, keys or chains. This can lead to a closed circuit and heat up the material.
• If the microphone units are to be operated by an external power supply, you can use the CA 2457 power supply/charger only.
• To align the gooseneck microphone on the MCW-D 521 / 523 microphone unit and to avoid twisting it too far and
causing premature wear, always grip the microphone by the bottom flexible section never by the microphone head
or by the rigid tube. The gooseneck must be bent no further than an angle of 90° maximum.
