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 side 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:

■

Cleaning the lens

■

Cleaning the projector case

■

Cleaning and replacing the air filter

■

Replacing the lamp

■

Resetting the lamp timer

■

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 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.
