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 clean.
Never remove any parts of the projector except the lamp. Contact your dealer if other 
parts need replacing.
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface.
Before cleaning any part of the projector, tu rn it off using the proper shutdown procedure 
(see  Shutting down the projector on page 51 ), 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.
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.
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 51  and unplug the power cord and let 
it cool down completely. 
• 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 ot her chemical detergents. These can damage the 
case.
