Maintenance
n Outer Case
Wipe off dirt and dust using a soft dry cloth.
• If the dirt is persistent, soak the cloth with water and wring it thoroughly before wiping. Dry off the projector with a
dry cloth.
• Do not use benzene, thinner, or rubbing alcohol, other solvents, household cleaners, or chemical treated dusters.
Using them may cause deterioration of the outer case.
n Front glass surface of the lens
Wipe off the dirt and dust off the front surface of the lens with soft clean cloth.
• Do not use a cloth that has an abrasive surface or a cloth that is moist, oily, or covered with dust.
• Do not use excessive force when wiping the lens as it is fragile.
Attention
The lens is made of glass. Impacts or excessive force when wiping may scratch its surface.
Please handle with care.
n Air filters
Perform the maintenance of the air filter units in following cases. If a “Filter warning” icon appears on the screen,
replace the filters immediately.
• The filter mesh is blocked, causing the filter warning icon appears on the screen and the <WARNING Indicator>
to light in red.
• The filter mesh is blocked, causing the internal temperature to rise, the <POWER Indicator> to light, and the
power to shut off. (When the power is shut off, the <POWER Indicator> blinks in red and the <WARNING Indica-
tor> blinks faster than usual.)
Before replacing the unit
When you perform maintenance or replacement of the parts, make sure to turn off the power and disconnect the
power plug from the wall outlet.
Maintenance
Air filter units
Filter prevents dust from accumulating on the optical ele-
ments inside the projector. Should the filter become clogged
with dust particles, it will reduce cooling fans’ effectiveness
and may result in internal heat buildup and adversely affect
the life of the projector. If a “Filter warning” icon appears on
the screen, replace the filters immediately.
n Replacement of the air filter units
1) Remove the air filters.
• Turn over the projector and pull out the filter cover (bot-
tom); pull up the handle and take out the whole filter

Press up the latches and pull out the filter cover (side);
pull out the handle and take out the side filter.
2) Replace the air filter units.
