MCW-D 50 – Setting up

6.2 Charging Process

1. Connect the charger to AC power and switch it on. The switch will illuminate.
2. Put the switched-off microphone units into the charging compartments. If microphone units are switched on, they are switched off
automatically. When the microphone units are used again, they must be switched on.
3. The charging process is indicated by the gooseneck LED ring and can be seen from the outside through a window.

Note:
• If an error has occurred, try to restart the charging process. If the LEDs are still flashing rapidly, please contact your
beyerdynamic dealer.
• After some time the capacity of the rechargeable batteries is reduced technically. This will reduce the operating time.
• It is normal that the rechargeable batteries are heated up during the charging process.
• Clean the charging contacts with spirit or isopropyl alcohol from time to time.

CD 13 Charger in CC 13 Case

• With the CD 13 charger integrated in the CC 13 transport case, it is possible to charge a maximum of 12 MCW-D 531 / MCW-D 533
microphone units. The battery state can be seen from the outside through a window.
• The CC 13 transport case can be extended with another CD 13 charger for 12 microphone units. Because of a possible instability more
than two CD 13 chargers must not be piled up.
• The CD 13 charger has a compartment for storing accessories such as headphones.
• The top foam cover inside the CD 13 charger is used as transportation safety device and must be removed before and during the
charging process.
7.1

How to use the Charger

• To achieve a 100% battery capacity all microphone units should have 2 complete charging cycles (charging and discharging) at least.
Only after several charging and discharging cycles the rechargeable batteries will achieve their full capacity.
• MCW-D 531 / 533 microphone units are fitted with high-performance nickel-metal hybrid (NiMH) batteries. These guarantee operating
times of approx. 30 hours. It takes about 3.5 hours to recharge.
• The service life of the batteries largely depends on the manner in which they are looked after and on how well the user recharges them.
To extend the service life of the batteries for as long as possible, the following charging cycle is recommended:
– Do not keep the microphone units in the charging case when it is switched on.
– Only put the microphone units in the charging case before a conference / application and fully charge them until the "fully charged"
status is shown.
– In particular, when the microphone units are inserted, the charging case should not be constantly switched on and off. For each
charging cycle, there is an initial 5-minute charge to check the battery status. If the case with the microphone units is switched on
every day (for example, because the mains is switched off automatically or by a cleaner), the microphone units will be slowly but
constantly overcharged and this will damage the batteries.
– The NiMH batteries used minimise the so-called "memory effect" but their capacity is reduced when they are only partially discharged
on a regular basis. For this reason, the microphone units should be fully discharged every three months until they switch off
automatically. They can then be fully recharged. This procedure can, if necessary, be repeated a second time.
– If, despite this measure, the microphone unit does not operate for a sufficiently long period of time, the battery has reached the end
of its service life and must be replaced. The typical service life of the battery is greatly dependent on whether or not the above points
are observed. This is why batteries are not covered by warranties. If the above points are observed, a battery typically has a service life
of at least two years or 1000 complete charging cycles, depending on which occurs first.
7.2 Charging Process
1. Remove the transportation safety device. Connect the charger to AC power and switch it on. The switch will illuminate.
2. Put the switched-off microphone units into the charging compartments. If microphone units are switched on, they are switched off
automatically. When the microphone units are used again, they must be switched on.
3. The charging process is indicated by the gooseneck LED ring and can be seen from the outside through a window.
a) Gooseneck LED ring is flashing red. . . . . . . . . . . . . . . . . . . Battery is charged
b) Gooseneck LED ring illuminates red permanently . . . . . . . . Battery is full
c) Gooseneck LED ring is flashing red rapidly . . . . . . . . . . . . . Error
Note:
• The aluminium sheet which is used as a cover for the battery compartment at the bottom of the MCW-D 53x microphone unit
can heat up during the charging process. This is the reason why you should only touch the top of the microphone unit when
removing it from the charging compartment; otherwise you can burn your hand.
• If an error has occurred, try to restart the charging process. If the LEDs are still flashing rapidly, please contact your
beyerdynamic dealer.
• After some time the capacity of the rechargeable batteries is reduced technically. This will reduce the operating time.
• It is normal that the rechargeable batteries are heated up during the charging process.
• Clean the charging contacts with spirit or isopropyl alcohol from time to time.
