overheating and damage the projector. 
To clean the air filters, follow these steps:
1. Turn off the projector and unplug the power cord.
2. To clean the filters, EPSON recommends using a small vacuum 
cleaner designed for computers and...

The projection lamp lasts up to 7000 hours. (Lamp life results will 
vary depending upon environmental conditions and usage.) Turn the 
projector off when not in use. Continuous 24-hour-a-day use may

When the lamp nears the end of its life (as determined from projector 
usage), the message 
LAMP REPLACE appears on the screen and the 
lamp warning light   flashes orange. To maintain projector 
brightness and image...
