Using Basic Projector Features
Clean the projector's lens periodically, or whenever you notice dust or smudges on the surface.
To remove dust or smudges, gently wipe the lens with clean and dry lens-cleaning paper.
If the lens is dusty, blow off dust using a blower, and then wipe the lens.
Warning
Before cleaning the lens, turn off the projector and unplug the power cord.
Do not use any flammable gas sprays such as air dusters to blow off dust. The high heat generated by the projector may cause a fire.
Do not wipe the lens right after you turn off the projector. Doing so could damage the lens.
Do not use any harsh materials to clean the lens and do not subject the lens to any impacts; otherwise, it could be damaged.
