Care of the projector
Your projector needs little maintenance. The only thing you need to do on a regular basis
is to keep the lens and case clean.
Never remove any parts of the projector. Contact your dealer if any part needs replacing.
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface.
• Use a canister of compressed air to remove dust.
• If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens
cleaner and gently wipe the lens surface.
• Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or volatile
solvent, such as alcohol, benzene, thinner or insecticide. Using such materials or
maintaining prolonged contact with rubber or vinyl materials may result in damage to
the projector surface and cabinet material.
Cleaning the projector case
Before you clean the case, turn the projector off using the proper shutdown procedure as
described in "Shutting down the projector" on page 38 and unplug the power cord.
• To remove dirt or dust, wipe the case with a soft, lint-free cloth.
• To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral pH
detergent. Then wipe the case.
Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the case.
