Cleaning the air filter and air

When dust builds up on the air filter or the air intake
vent, or the message “The projector is overheating.
Make sure nothing is blocking the air vents, and clean or
replace the air filter” is displayed, remove any dust from
the air filter and the air intake vent using a vacuum
cleaner.

Maintenance
If dust collects on the air filter or the air intake vent 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.
Clean the 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.
Use a commercially available cloth for cleaning glasses
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.
