Charging the rechargeable battery

To minimize charging time and allow you to monitor the charge level, you should switch off the transmitter and/or receiver before charging the battery.

However, the transmitter and receiver can also be charged while in operation.



  1. Plug the small end of the USB charging cable into the USB port on the transmitter or receiver.
  2. Plug the large end of the USB charging cable into the USB port on a conventional USB power supply unit.
  3. Plug the USB power supply unit into the wall socket.
    The status LED indicates the charge level.
