Maintenance
Your projector needs little maintenance. All you need to do on a regular basis is keep the lens 
clean. You also may need to clean the air filter to prevent overheating.
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 . 
The only parts you should replace are the air  filter and the lamp. If another part needs 
replacing, contact your deal er or a qualified servicer.
Cleaning the Lens
