Care of the projector
To care for your projector, clean the lens and projector case on a regular basis, following the
instructions below.
Never remove any parts of the projector except the user-replaceable lamp. Contact your dealer if other
parts need replacing.
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface.
CAUTION: HOT SURFACE! Before cleaning the lens, turn the projector off, unplug the power
cord, and allow the projector to cool for at least 45 minutes.
1. Use a canister of compressed air to remove dust (available from building hardware or
photographic suppliers).
2. If there is stubborn dirt or smudge marks, use a photographic lens brush or a clean, soft lens
cloth (moistened with lens cleaner, if necessary) to gently wipe the lens surface.
NEVER touch the lens with your bare hands or rub the lens with abrasive materials (products such as
paper towels can damage the lens coating). ALWAYS use a photographic lens brush or lens cleaning
cloth and solution.
NEVER attempt to clean the lens while the projector is on or while it is still hot from previous use.
Cleaning the projector case
CAUTION: HOT SURFACE! Before cleaning the lens, turn the projector off, unplug the power
cord, and allow the projector to cool for at least 45 minutes.
1. To remove dirt or dust, wipe the case with a soft, dry, lint-free cloth.
2. If the soiling is severe, dip the cloth in a neutral detergent diluted in water, wring well, and gently
wipe off the dirt, then finish up by wiping with a dry cloth.
Never use wax, alcohol, benzene, thinner, or other chemical detergents. These products can damage the
case.
Storing the projector
If you need to store the projector for an extended time, follow these guidelines:
1. Make sure the temperature and humidity of the storage area are within the recommended range
for the projector. Please refer to the Specifications page in this manual or consult your dealer.
2. Retract the adjuster feet.
3. Remove the batteries from the remote control.
4. Pack the projector in its original packing (preferred) or equivalent packing materials.
Transporting the projector
Ship the projector in its original packing (preferred) or equivalent packing materials. If you carry the
projector yourself, use a protective, non-abrasive carrying case.
WARNING
• Request cleaning and maintenance of a ceiling-mounted unit from your projector dealership.
Attempting to clean/replace the lamp at a high site by yourself may cause you to drop down,
thus resulting in injury.
