Warning:

•Do not use flammable solvents (benzene, thinner, etc.) and flammable aerosols when cleaning the projector body and lens. Flammable substances may ignite causing fire or breakdown while the lamp is illuminating.

•Be sure to turn off the lamp and unplug the power cord from the wall outlet before you perform any maintenance on the projector.

•Do not spray insecticide on or inside the projector.

Cleaning of the lens
