Projector Maintenance
140
You may need to clean the projector's lens periodically, and clean the air filter
and air vents to prevent the projector from overheating due to blocked
ventilation.
The only parts you should replace are the air filter, remote control batteries,
and lens. If any other part needs replacing, contact Epson or an authorized
Epson servicer.
Warning
Before cleaning any part of the projector, turn it off and unplug the power cord.
Never open any cover on the projector, except as specifically explained in this
manual. Dangerous electrical voltages in the projector can injure you severely.
