Cleaning the lens

ensure not to scrape or hit the lens.

■ Use a vacuum cleaner to clean dust from the ex-
haust vent and the intake vent.

■ When the dirt is hard to remove, soak a cloth in a
mild detergent diluted with water, wring the cloth
well and then wipe the projector.
Strong cleaning detergents may discolor, warp or
damage the coating on the projector. Make sure to
test on a small, inconspicuous area on the projec-
tor before use.
