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.
CAUTION
Be sure to read the separate Safety Instructions/World-Wide Warranty
Terms before cleaning.

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.
CAUTION
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.
CAUTION
Do not rub the lens with harsh materials or subject the lens to shocks,
as it can easily become damaged.

Cleaning the Air Filters and Air Intake Vent

If dust collects on the air filter or the air outlet, 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.
TIP
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 "Appendices: Optional Accessories".
