Precautions
On safety
• Check that the operating voltage of your unit is
identical with the voltage of your local power
supply.
• Should any liquid or solid object fall into the cabinet,
unplug the unit and have it checked by qualified
personnel before operating it further.
• Unplug the unit from the wall outlet if it is not to be
used for several days.
• To disconnect the cord, pull it out by the plug. Never
pull the cord itself.
• The wall outlet should be near the unit and easily
accessible.
• The unit is not disconnected to the AC power source
(mains) as long as it is connected to the wall outlet,
even if the unit itself has been turned off.
• Do not look into the lens while the lamp is on.
• Do not aim the laser at people or not look into the
laser transmitter.
• Do not place your hand or objects near the
ventilation holes — the air coming out is hot.
• Be careful not to catch your fingers by the adjuster
when you lift up the projector. Do not push hard on
the top of the projector with the adjuster out.
On illumination
• To obtain the best picture, the front of the screen
should not be exposed to direct lighting or sunlight.
• Ceiling-mounted spot lighting is recommended. Use
a cover over fluorescent lamps to avoid lowering the
contrast ratio.
• Cover any windows that face the screen with opaque
draperies.
• It is desirable to install the projector in a room where
floor and walls are not of light-reflecting material. If
the floor and walls are of reflecting material, it is
recommended that the carpet and wall paper be
changed to a dark color.
On preventing internal heat build-up
After you turn off the power with the I /
1
key on the
Remote Commander or on the control panel, do not
disconnect the unit from the wall outlet while the
cooling fan is still running.
Caution
The projector is equipped with ventilation holes
(intake) on the bottom and ventilation holes (exhaust)
on rear. Do not block or place anything near these
holes, or internal heat build-up may occur, causing
picture degradation or damage to the projector.
On cleaning
• To keep the cabinet looking new, periodically clean
it with a soft cloth. Stubborn stains may be removed
with a cloth lightly dampened with a mild detergent
solution. Never use strong solvents, such as thinner,
benzene, or abrasive cleansers, since these will
damage the cabinet.
• Avoid touching the lens. To remove dust on the lens,
use a soft dry cloth. Do not use a damp cloth,
detergent solution, or thinner.
• Clean the filter at regular intervals every 300 hours.
On repacking
• Save the original shipping carton and packing
material; they will come in handy if you ever have to
ship your unit. For maximum protection, repack your
unit as it was originally packed at the factory.
On LCD projector
The LCD projector is manufactured using high-
precision technology. You may, however, see tiny
black points and/or bright points (red, blue, or green)
that continuously appear on the LCD projector. This is
a normal result of the manufacturing process and does
not indicate a malfunction.
