our projector needs little maintenance. All you have 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 filters at the side and base of 
the projector. A clogged air filter can block ventilation needed to cool 
the projector.

The only parts you should replace are the lamp and air filters (when 
you order a new lamp, replacement filters come with it). If any other 
part needs replacing, contact your dealer or a qualified servicer.

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 
cover. 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.
