GMU Series: how to charge

The USB to micro USB cable charges the GT-10 transmitter, the R10 and R20 receivers, and the MT-10 microphone transmitter. The HSL-100's BT-10 body pack transmitter runs on 1 AA battery, so it has no charging port.

How to charge

Turn the device off. Charging while it's powered on draws current at the same time, which means longer charge times and shorter battery life over the long run.
Connect the micro USB cable to the device.
Plug the other end into a USB charging port or a qualified power adapter.

Charging status

While the GT-10 transmitter, R10 receiver, or R20 receiver is charging, the battery LED lights up green. When the battery is full, the LED turns off.
