Maintaining the Projector
Your projector needs little maintenance. All you have to do is keep 
the lens clean and periodically clean the air filters at the side and 
bottom 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 filter. If any 
other part needs replacing, contact your dealer or a qualified servicer.

lens.

1. Turn off the projector. Wait for the 
Power light to stop flashing, 
then unplug the power cord.
2. Turn the projector upside down.
3. To clean the intake vents, use a small vacuum cleaner...
