Cleaning
You should clean the projector if it becomes dirty or if the quality of
projected images starts to deteriorate.
Warning
Do not use sprays containing a flammable gas to remove dirt or dust which is
adhering to parts such as the lens or filter of the projector.
This could cause a fire due to the high temperature of the lamps inside the unit.
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.
Caution
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.
Cleaning the Lens
Use a commercially available cloth for cleaning glasses 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 Filter
Clean the air filter and the air intake vent when the following message is
displayed or the Filter indicator is flashing green.
"Time to clean the air filter."
"Clean or replace the air filter."
Caution
• 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.
• If the air filter is stained yellow with tobacco smoke, it cannot be cleaned. In this
case, replace it with a new air filter. s
• Do not rinse the air filter in water. Do not use detergents or solvents.
• When using a brush for cleaning, use one with long soft bristles, and brush it lightly.
If it is brushed too strongly, dust will be ground into the air filter and cannot be
removed.
