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. Contact your dealer if other parts need 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.
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 proper shutdown procedure as
described in "Shutting down the projector" on page 28 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.
Storing the projector
If you need to store the projector for an extended period of time, please follow the
instructions below:
• Make sure the temperature and humidity of the storage area are within the
recommended range for the projector. Please refer to "Specifications" on page 64 or
consult your dealer about the range.
• Retract adjuster feet.
• Remove battery from the remote control.
• Pack the projector in its original packing or equivalent.
