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 coud be a cause of the fire for the high temperature of 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.
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.

Cleaning the Lens

Use a commercially available cloth for cleaning glasses to gently wipe
the lens.
Attention
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."
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.
•
If the air filter is stained yellow with tobacco smoke, it cannot be cleaned.
In this case, replace it with a new air filter.

confirmation buzzer beeps twice, disconnect the power cable.
