Performing a system reset can be beneficial for several reasons, particularly when you're experiencing persistent issues with your computer that other troubleshooting steps have not resolved. To reset your Lü system correctly, please follow these steps:
1. Turn off the computer and the projector.
2. Find the breaker on which Lü is installed and turn it off for 2 minutes.

We recommend identify the breaker if it's not done already.
3. When the breaker is back on, turn the projector on again. The computer will automatically reboot.

It's very important to turn off the computer and the projector before turning off the electrical breaker to prevent any damage to the devices.
