Important Safety Information
- Electrical Hazard: Always disconnect power to the device before attempting to install or replace the light bulb. Failure to do so may result in electric shock or injury.
- Burn Hazard: Light bulbs can become extremely hot during operation and immediately after being turned off. Allow the bulb to cool completely before handling.

- No Light:
- Ensure the projector is properly plugged into a working power outlet.
- Verify that the bulb is securely seated in its socket. Remove and re-insert if necessary, ensuring correct alignment.
