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 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 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.
