CD 12 Charger in CC 12 Case

• With the CD 12 charger integrated in the CC 12 transport case, it is possible to charge a maximum of 10 MCW-D 521 / MCW-D 523
microphone units. The battery state can be seen from the outside through a window.
• The CC 12 transport case can be extended with another CD 12 charger for 10 microphone units. Because of a possible instability more
than two CD 12 chargers must not be piled up.
• The CD 12 charger has a compartment for storing accessories such as headphones.

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 521 / 523 microphone units are fitted with high-performance nickel-metal hybrid (NiMH) batteries. These guarantee operating
times of approx. 20 hours. It takes about two hours to recharge the two systems.
• 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.
• This operating mode is only possible in conjunction with a PC using the
MCW-D 50 Conference software or media control system (AMX
Cue etc.).
• The request-to-talk is registered in the system by pressing the microphone
button of the microphone unit.

• The allocation is made by the operator at the PC or touch screen of the media
control system.
• The LED is illuminated red to indicate the request-to-talk.
