On Cleaning
Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a
damp cloth for cleaning.
- To keep the cabinet looking brand-new, periodically clean it with a soft cloth. Stubborn stains may be removed
with a cloth lightly dampened with mild detergent solution. Never use strong solvents, such as thinner or ben-
zine, or abrasive cleaners, since these will damage the cabinet.
- To ensure the highest optical performance and resolution, the projection lenses are specially treated with an
anti-reflective coating, therefore, avoid touching the lens. To remove dust on the lens, use a soft dry cloth.
On Repacking
Save the original shipping carton and packing material; they will come in handy if you ever have to ship your
equipment. For maximum protection, repack your set as it was originally packed at the factory.
On Illumina
tion
In order to obtain the best quality for the projected image, it is essential that the ambient light which is allowed to
fall on the screen be kept to an absolute minimum. When installing the projector and screen, care must be taken
to avoid exposure to ambient light directly on the screen. Avoid adverse illumination on the screen from direct
sunlight or fluorescent lighting fixtures. The use of controlled ambient lighting, such as incandescent spot light or
a dimmer, is recommended for proper room illumination. Where possible, care should also be taken to ensure
that the floors and walls of the room in which the projector is to be installed are non-reflecting, dark surfaces.
Brighter surfaces will tend to reflect and diffuse the ambient light and hence reduce the contrast of the projected
image on the screen.
