If your U3 remote becomes unresponsive, freezes on a blue/white screen, or encounters any other system glitch, you can perform a forced hard reboot by pressing the physical button on the remote.
Follow these steps:
Locate the Air Mouse (cursor) button on the right side of the U3 remote.
Press and hold down this button continuously for about 10 seconds.
Release the button when the remote’s display turns off and restarts automatically.
The remote will power-cycle and reboot into normal operation. This process does not erase any settings or paired devices—it simply resets the internal firmware state.
Note: If the issue persists after the hard reboot, please check the battery level or contact our support team.
