Maintenance
Care of the projector
Your projector needs little maintenance. The only thing you have to do on a regular basis is keep the lens clean.
Never remove any parts of the projector. Contact your dealer or local customer service center if the projector fails to operate as expected.
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface.
Before cleaning any part of the projector, turn it off using the proper shutdown procedure (see Shutting down the projector on page 40 ), unplug the
power cable, and let it cool down completely.
• 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 cleaning any part of the projector, turn it off using the proper shutdown procedure (see Shutting down the projector on page 40 ), unplug the
power cable, and let it cool down completely.
• To remove dirt or dust, wipe the case with a soft, dry, lint-free cloth.
• To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral detergent. Then wipe the case.
Never touch the lens with your finger or rub the lens with abrasive materials. Even paper towels can damage the lens coating. Only ever use a proper photographic lens
brush, cloth, and cleaning solution. Do not attempt to clean the lens while the projector is switched on or is still hot from previous use.
Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the case.
