damped with water, or water and neutral detergent, and wipe dry with a soft, dry

cloth.

Turn off the projector and remove the AC power cord from the power outlet

before beginning maintenance work.

Make sure the lens is cool before cleaning.

Do not use detergents or chemicals other than those noted above. Do not
