Maintenance

This section describes maintenance tasks such as cleaning the projector and
replacing consumable parts.

Cleaning

You should clean the projector if it becomes dirty or if the quality of
projected images starts to deteriorate.
CAUTION
Be sure to read the separate Safety Instructions/World-Wide Warranty
Terms before cleaning.

Cleaning the Projector Case

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.
CAUTION
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.

Cleaning the Lens

Use a commercially-available air blower, or use a lens cleaning paper 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 Filters and Air Intake Vent

If the air filters become clogged with dust, or if the message "The projector
is overheating. Clean or replace the air filter and lower the room
temperature." appears on the screen, clean the air filters and the air intake
vent.
If the air filters become clogged with dust, it can cause overheating and
damage the projector.
Turn the projector upside-down and use a vacuum cleaner to clean the air
intake vent.
TIP
• If the air filters are broken or if the warning message reappears after
they have been cleaned, they should be replaced. Replace with a new
air filter. See "Appendices: Optional Accessories".
• Spare lamps are provided with a spare air filter. The air filter should
also be replaced when the lamp is replaced.
