Maintenance

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. Please be sure to turn off 

the projector and let it cool down completely before cleaning the lens.

•  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 you clean the case, turn the projector off using the proper shutdown procedure as 

described in 

"Shutting down the projector" on page 34

 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 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 53

 or 

consult your dealer about the range.

•  Retract the adjuster feet.
•  Remove the battery 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. 

When you carry the projector yourself, please use the original box or the soft carry case.
