Cleaning the Lens
Clean the lens whenever you notice dirt or dust on the surface. Lightly wipe the
lens surface with a soft, dry, lint-free cloth.
To remove dirt or stains on the lens, moisten a soft cloth with an alcohol-based
cleaner and gently wipe the lens surface.
Cleaning the Projector Case
To clean the projector case, first unplug the power cord. 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, benzine, thinner, or other chemical detergents. 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 periodically, it can become
clogged with dust and prevent the projector from being ventilated properly. This
can cause overheating and damage the projector.
