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.
Be sure to read the separate Safety Instructions/World-Wide Warranty Terms booklet for details
on safe handling of the projector during cleaning.

Cleaning the air filter

If the air filter becomes blocked with dust and the message
"The projector is overheating. Make sure nothing is blocking
the air vent, and clean or replace the air filter" is displayed,
clean the air filter.
Turn the projector upside-down and use a vacuum cleaner to
clean the air filter
If the air filter becomes clogged with dust, it can result
in overheating which may cause operating problems or
reduce the operating life of the optical parts. It is
recommended that you clean the air filter about once
every three month. If using the projector in a dusty
location, the air filter should be cleaned more often.

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.
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

To clean the lens it is preferable to use an air blower
purchased for the purpose. But alternatively you can wipe it
gently clean with a spectacle-cleaning cloth.
Do not rub the lens with harsh materials or subject the
lens to shocks, as it can easily become damaged.
