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 may cause a fire.
Caution:
Do not use glass cleaner or any harsh
materials to clean the lens and do not subject the lens to any
impacts; you may damage it. Do not use canned air, or the gases may
leave a residue. Avoid touching the lens with your bare hands to
prevent fingerprints on or damage to the lens surface.
