4. MCW-D 10 Charging Unit
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.

4.1 Charging Process

1. Connect the charger to AC power and switch it on. The LED 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 green LEDs on the outside.

beyerdynamic dealer.

4.2 Forming Mode

The LE-D 10 charging units are equipped with a forming mode for the rechargeable batteries inside the microphone units. The
batteries are formed and charged at the factory. If you have not used the microphone units for several months, you should form the
batteries before you set up the microphone units. Do this as described in the following:
• First of all remove all microphone units from the charging compartments.
• After switching on the charger press the buttons in the bottom of the two furthest charging compartments (next to the contact
pins in the round gap).
• Pressing one of these buttons will activate the forming mode for 5 charging compartments. The LEDs will flash rapidly.
• Then put the microphone units into the charging compartments. The LEDs will flash short and long.
• When the green LEDs are permanently on, then the battery is full.
Caution:
Only form empty or partly discharged batteries, but never full batteries!
Do not switch off the charging unit during the forming mode, as this will interrupt the forming mode.
The forming mode will be terminated automatically when the microphone units are fully charged or when the charger is switched
off.
5. Battery Charging with external Charger
The MCW-D microphone units can be also charged with the CA 2456 external charger which is connected to the multi-function
socket (1).
Important:
The automatic switching off of the microphone units when they are charged is not possible with the CA 2456. Therefore, the
microphone units must be switched off manually (or via the MCW-D 100 control unit) before charging.
