LE-D 10 Charger in MCW-D 10 Case

With the integrated LE-D 10 charger in the MCW-D 10 transport case, it is possible to charge up to 10 microphone unit
batteries. The battery state is indicated on the outside of the case.
The MCW-D 10 transport case can be extended with more LE-D 10 chargers for 10 microphone units each.

Safety Information

• When installing the unit make sure that the plugs can be accessed easily.
• The unit must be connected to an isolated ground receptacle.
• Never expose the unit to water or excessive humidity. Do not install near swimming pools, spas, in a wet basement or in other
excessively humid environments.
• Never put any objects filled with liquids (e.g. vases or drinking vessels) onto the unit.
• Do not install or use this unit near sources of high heat, such as radiators, heat registers, flood lamps, spotlights, stoves, or other
appliances.
• Always route cables running to the unit where they will not be pinched or cut by heavy or sharp objects.
• Verify that the voltage rating of the unit matches that of the AC mains outlet you are to use. If you connect the unit to the wrong
voltage, you may seriously damage it.
• This unit needs a sufficient ventilation. Therefore, never cover the ventilation grilles. Leave a minimum distance of 20 cm around
the unit.
• Never place burning objects (e.g. candles) onto the unit.
• Do not remove the foam material from the LE-D 10 charger. There are no parts inside the LE-D 10 charger that need
servicing.
• If you transport the microphone units with the MCW-D 10 charging/transport case, please make sure to always insert the
transportation protection (Order # 470.074) for the charging contacts into the appropriate charging compartment. Otherwise, the
charging pins can be damaged.

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 200 microphone units are fitted with high-performance nickel-metal hybrid (NiMH) batteries. These guarantee
operating times of more than 8 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.
