Please make sure the power plug is unplugged before cleaning.
Do not use pesticides or other volatile chemicals on the projector or lens. Do not let
rubber or vinyl products contacts the projector for a long time, which will damage the
coating and make it peeled off.

that stuck with diluted neutral detergent, then dry with a clean and dry cloth. Please
pay more attention if used with chemical fiber cloth.
2. Don’t use thinner, benzene or any other solvents to avoid quality reduction or coating
peeling off etc.
3. A brush can be inserted into the front of the vacuum cleaner to remove dirt inside the
vents. Please don’t use vacuum cleaner with no connector, or clean with vents directly.
4. Please don’t scrape the machine with nails or any other hard objects so as to avoid
scratches.
· Lens Cleaning
1. Clean lens with the same method for camera lens: please use professional blow dryer
or cleaning paper for glasses, ensure lens are not scratched.
