Maintenance
This section describes maintenance tasks such as cleaning the projector and
replacing consumable parts.
Cleaning
You should clean the projector if it becomes dirty or if the quality of
projected images starts to deteriorate.

Cleaning the Air Filter and Air Intake Vents
If dust collects on the air filter or the air intake vents, it can cause the
internal temperature of the projector to rise, and this can lead to problems
with operation and shortening of the optical engine's service life.
It is recommended that you clean these parts at least once every three
months. Clean them more often than this if using the projector in
particularly dusty environments.
Cleaning the Projector's Surface
Clean the projector's surface by wiping it gently with a soft cloth.
If the projector is particularly dirty, moisten the cloth with water
containing a small amount of neutral detergent, and then firmly wring the
cloth dry before using it to wipe the projector's surface. Then wipe it again
with a soft, dry cloth.
Do not use volatile substances such as wax, alcohol or
thinner to clean the projector's surface. These can
cause the projector to warp and make the coating finish
peel off.
Cleaning the Lens
Use a commercially-available air blower, or use a lens cleaning paper to
gently wipe the lens.
Do not rub the lens with harsh materials or subject the
lens to shocks, as it can easily become damaged.

If the air filters are broken or if the warning message
reappears after they have been cleaned, they should be
replaced. Replace with a new air filter. See "Replacing
the Air Filter". sp.62
