Maintenance
This section describes maintenance tasks such as cleaning the projector and replacing consumable parts.
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 a lens cleaning paper to gently wipe the lens.
If the air filter becomes clogged with dust, it can cause overheating and damage the projector.
Stand up the projector in order to prevent dust getting inside the projector, and then use a vacuum cleaner to
clean away the dust from the air filter.

Cleaning the Air Filter
•••• If the air filter is difficult to clean or if it is broken,
it should be replaced. Contact your dealer for a
spare air filter.
•••• Replacement lamps are provided with a spare
air filter. The air filter should also be replaced
when the lamp is replaced.
Be sure to read the Safety Instructions in this manual for details on safe handling of
the projector during cleaning.
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.
Do not rub the lens with harsh materials or subject the lens to shocks, as it can
easily become damaged.
