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 one hour.
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 one hour.
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.
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.
