How do I clean the air filter?
Remove the filter cover, take out the filter, and gently vacuum or wash it with mild soap. Dry thoroughly before reinstalling. Clean every 100 hours of use.
Why is the projector overheating?
Check for blocked ventilation slots or a dirty air filter. Ensure the projector has at least 50 cm clearance on all sides. If the problem persists, the internal fan may need service.

Can I use the projector without a screen?
Yes, you can project onto a white wall or other flat surface. However, a proper projection screen improves brightness and contrast.
