Maintenance
The projector needs little maintenance. You should keep the lens clean
as dust, dirt or spots will project on the screen and diminish image
quality. You will also need to clean the air filter located at the bottom
of the projector periodically. It is important to keep the air filter clean
because a clogged air filter prevents proper ventilation which is
necessary to cool the projector and prevent it from overheating. The
only part you should replace yourself are the lamp and the air filter. If
any other parts need replacing, contact your dealer or qualified service
personnel. When cleaning any part of the projector, always switch off
and unplug the projector first.
Warning: Never open any of the covers on the projector
except the lamp and air filter covers. Dangerous electrical
voltages inside the projector can cause severe injury.
Except as specifically indicated in this Instruction Manual,
do not attempt to service this product yourself. Refer all
servicing to qualified service personnel.
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 Housing
To clean the projector housing, first unplug the power cable. To
remove dirt or dust, wipe the housing 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 housing. Do not use alcohol,
benzene, thinners or other chemical detergents as these can cause
damage to the housing.
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.
