Turn off the projector and unplug the power cord from the electrical outlet. 2.
5500.book Page 112 Wednesday, August 4, 1999 4:41 PM 4. The air filter is attached to the inside of the filter cover. It is recommended that you use a small vacuum cleaner designed for computers and other office equipment to clean the filter. If you don’t have one, use a dry, lint-free cloth. If the dirt is difficult to remove or if the filter is torn, replace the air filter. Note: An air filter comes with each replacement lamp. Contact your dealer or call EPSON Accessories at (800) 873-7766 in the U.S.
