Maintaining the Projector
Your projector needs little maintenance. All you have to do is keep 
the lens clean and periodically clean the air filter and vent. A clogged 
air filter or vent can block ventilation needed to cool the projector.
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.
