Your projector needs little maintenance. The only thing you have to do on a regular basis is keep
the lens clean. Never remove any parts of the projector except the lamp. Contact your dealer or
local customer service center if the projector fails to operate as expected.
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface. Before you attempt to clean the
lens, turn the projector off, unplug the power cable, and leave it several minutes to cool completely.
Use a canister of compressed air to remove dust. (Available from building hardware or
photographic suppliers.)
If there is stubborn dirt or smudge marks, use a proper photographic lens brush or moisten a clean
soft lens cloth with lens cleaner to gently wipe the lens surface.
Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or volatile solvent, such
as alcohol, benzene, thinner or insecticide. Using such materials or maintaining prolonged contact
with rubber or vinyl materials may result in damage to the projector surface and cabinet material.
Never touch the lens with your nger or rub the lens with abrasive materials. Even paper towels can damage the lens
coating. Only ever use a proper photographic lens brush, cloth, and cleaning solution. Do not attempt to clean the lens
while the projector is switched on or is still hot from previous use. Be sure to turn off the projector and let it cool
down completely before cleaning the lens.
Cleaning the projector case
Before you attempt to clean the case, turn the projector off, unplug the power cable, and leave it
several minutes to cool completely.
To remove dirt or dust, wipe the case with a soft, dry, lint-free cloth.
To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral detergent. Then
wipe the case.
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:
• Make sure the temperature and humidity of the storage area are within the recommended
range for the projector. Please refer to “Specications” on page 62 in this manual or consult
your dealer about the range.
• Retract the adjuster feet.
• Remove the batteries from the remote control.
