Clean
the projector's lens periodically, or whenever you notice dust or
smudges on the surface. Make sure you unplug the
projector before cleaning the lens.
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 wipe the lens
immediately after turning off the light source; otherwise, it could
be damaged. Do not use glass cleaner or harsh materials to
clean the lens and do not subject the lens to any impacts;
otherwise, you may damage the lens. Do not use canned air to clean
the lens; the gases may leave a residue. Avoid touching the lens
with your bare hands to prevent fingerprints on or damage to the
lens surface. Do not use cleaning products that contain ammonia;
the protective coating on the lens could be damaged.
