Maintaining and 
Transporting the Projector
Y
our 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.

warning
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 and 
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 
personnel.
