Cleaning the Lens
Clean the lens whenever you notice dirt or dust on the surface. Wipe
the lens surface gently with a soft, dry, lint-free cloth.
To remove dirt or stains on the lens, moisten a soft cloth with water
and a neutral detergent and gently wipe the lens surface.
Cleaning the Projector Case
To clean the projector case, first unplug the power cable. To remove
dirt or dust, wipe the casing with a soft, dry, lint-free cloth. To
remove stubborn dirt or stains, moisten a soft cloth with water and a
neutral detergent. Then wipe the casing.
Do not use alcohol, benzene, thinners or other chemical detergents
as these can cause the casing to warp.
Cleaning the Air Filter
The air filter, which is located at the bottom of the projector, should
be cleaned after every 100 hours of use. If it is not cleaned periodi-
cally, it can become clogged with dust and prevent the projector from
being ventilated properly. This can cause overheating and damage the
projector.
