Maintenance
Care of the projector
Your projector needs maintenance from time to time, depending on the environmental circumstances, and
should be done by authorized service technicians only. Contact your dealer for instructions.
The only thing you can do yourselves on a regular basis is to keep the lens and cabinet 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 rub the lens with abrasive materials.
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 42 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.
• Flammable substances may ignite causing fire or breakdown while the lamp is illuminating.
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 67 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.
