To restart your DxO ONE:
- Plug the DxO ONE into a USB wall charger and have it charge for at least 2 hours, even if the OLED stays OFF.
- After the DxO ONE has charged for 2 hours or more, unplug it from the charger.
- Push the RESET button.
- Plug the DxO ONE into a USB wall charger again. The OLED display should turn on and the DxO ONE will then be charging in standard mode (rather than in slow mode).
