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 except the lamp. 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), 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 cleaning any part of the projector, turn it off using the proper shutdown procedure (see Shutting
down the projector), 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 use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the case.
Storing the projector
To store the projector for an extended time:
• Make sure the temperature and humidity of the storage area are within the recommended range for
the projector. Refer to Specifications or consult your dealer about the range.
• Retract the adjuster feet.
• Remove the batteries from the remote control.
• Pack the projector in its original packing or equivalent.
Transporting the projector
It is recommended that you ship the projector with its original packing or equivalent.
