Maintaining and Transporting the Projector 63
Maintaining and
Transporting the Projector
Your projector needs little maintenance. All you need to do on a
regular basis is keep the lens clean. Any dirt or smears on the lens may
show up on your projected image.
You also need to periodically clean the air filter on the bottom of the
projector. A clogged air filter can block ventilation needed to cool the
projector and cause overheating.
The only parts you should replace are the lamp and air filter. If any
other part needs replacing, contact your dealer or a qualified servicer.
This chapter covers the following:

Transporting the projector
Before you clean any part of
the projector, turn it off and
unplug the power cord. Never
open any cover on the
projector, except the lamp an
filter covers. Dangerous
electrical voltages in the
projector can injure you
severely. Do not try to service
this product yourself, except as
specifically explained in this
User’s Guide. Refer all other
servicing to qualified service
