41 Using the projector
Additional information
Care of the projector
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.
1. Use a clean soft lens cloth to remove dust. (Available from building hardware or
photographic suppliers.)
2. 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.
3. 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 finger 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.
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.
1. To remove dirt or dust, wipe the case with a soft, dry, lint-free cloth.
2. 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:
1. Make sure the temperature and humidity of the storage area are within the
recommended range for the projector. Please refer to the Spec. page in this manual
or consult your dealer about the range.
2. Retract the adjuster feet.
3. Remove the batteries from the remote control.
4. Pack the projector in its original packing or equivalent.
Transporting the projector
