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 lens-cleaning
paper.
To remove stubborn smudges, moisten a soft, lint-free cloth with lens
cleaner and gently wipe the lens. Do not spray any liquid directly on
the lens.
Warning
Do not use a lens cleaner that contains flammable gas. The high heat generated
by the projector lamp may cause a fire.
Attention
Do not use glass cleaner or any harsh materials to clean the lens and do not
subject the lens to any impacts; otherwise, it could be damaged. Do not use
canned air, or the gases may leave a flammable residue.
