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 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.
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 8 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.
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 25 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.
