Maintenance Care of the projector You need to keep the lens and/or filter (optional accessory) clean on a regular basis. Never remove any parts of the projector. Contact your dealer when any part of the projector needs 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. CAUTION 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 46 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. CAUTION 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 63 or consult your dealer about the range. • Retract the adjuster foot. • 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. Using the dust filter (optional accessory) CAUTION • It is recommended to clean the dust filter every 100 hours after the dust filter is installed. • Be sure to turn off the projector and unplug it from power source before installing or detaching the filter. 57
