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 place your hand or objects near the
ventilation holes. The air coming out is
hot.
• Be careful not to have your fingers caught
by the adjuster. The powered tilt adjuster
of this unit automatically extends when the
power is turned on, and is put away
automatically when the power is turned
off. Do not touch the unit while the
adjuster is in operation. Adjust the
powered tilt adjuster carefully after its
automatic operation is completed.
• Do not spread a cloth or paper under the
unit.
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

key, 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) and ventilation holes
(exhaust). 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.
On LCD data projector
• The LCD data 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 data
projector. This is a normal result of the
manufacturing process and does not
indicate a malfunction.
