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 move the
shutter to the side and wipe the lens with lens-cleaning paper or a
soft, dry lens-cleaning cloth. After cleaning,
close the shutter.
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.Use a vacuum cleaner or a hand-held
air blower to remove any dust and lint on the lens.
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.
