The remote controller doesn't charge

Follow these steps to troubleshoot this issue and check if the issue is resolved after each step:

1. Check the ambient temperature and the temperature inside the remote controller. The remote controller may not charge if these temperatures are too high or too low.
2. Disconnect the AC adapter from the remote controller and the wall outlet, and then reconnect it.
3. Make sure that the AC adapter and the power cord are correctly connected.
4. If a USB cable is connected to the micro USB port (USB-B) of the remote controller, disconnect it.
5. Press and hold the power button for at least 10 seconds to force the remote controller to turn off.
6. If the issue still occurs, simultaneously press and hold the C2 (Custom 2) button and the power button for at least 10 seconds.
