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 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.
• 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 maitaining 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 45 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

below:

recommended range for the projector. Please refer to "Specifications" on page 62 or
consult your dealer about the range.

• Pack the projector in its original packing or equivalent.
