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.
Clean the projector case 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 case. Then wipe the case
again with a soft, dry cloth.
Use a commercially-available air blower, or use lens cleaning paper to
clean the lens.
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.

Cleaning the Lens
CAUTION
Be sure to read the separate Safety Instructions/World-Wide Warranty
Terms before cleaning.
CAUTION
Do not use volatile substances such as wax, alcohol or thinner to
clean the projector case. These can cause the case to warp and make
the coating finish peel off.
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
Turn the projector upside-down and
use a vacuum cleaner to clean the air
intake vent.
