What does the "Fu" error code mean on my Dragon 5 Connect, and how can I fix it?

The "Fu" code on your display usually indicates a connection or pairing error between your device and the app. Don't worry—it is easy to reset! Please follow these simple steps to clear the code and reconnect:

1. Power Down: Completely unplug the Dragon5 Connect from the electrical outlet.
2. Wait a Moment: Leave the unit unplugged for about 30 seconds to allow the internal electronics to reset.
3. Restore Power: Plug the device back into the wall socket.
4. Restart Pairing: Open your app and follow the standard "pairing" instructions to link your device again.

If the "Fu" code persists after these steps, a professional repair may be required to resolve the technical issue. Please contact our support team for further assistance.
