56 Cleaning
You should clean the projector if it becomes dirty or if the quality of
projected images starts to deteriorate.
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.
Cleaning the Lens
Use a commercially available cloth for cleaning glasses to gently wipe the
lens.
Cleaning the Air Filter and Air Intake Vent
Clean the air filter and the air intake vent when the following message is
displayed.
"The projector is overheating. Make sure nothing is blocking the air vent,
and clean or replace the air filter"
s
"How to replace the air filter" p.61
Attention
Do not use volatile substances such as wax, alcohol, or thinner to
clean the projector's surface. The quality of the case may change or
become discolored.
Attention
Do not rub the lens with harsh materials or subject the lens to
shocks, as it can easily become damaged.
Attention
If dust collects on the air filter it can cause the internal temperature
of the projector to rise, and this can lead to problems with operation
and shorten the optical engine's service life. Clean the air filter
immediately when the message is displayed.
q
• If a message is frequently displayed, even after cleaning, it
is time to replace the air filter. Replace it with a new air
filter.

• 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 a particularly dusty environment.
