Precautions
Safety
• Check that the operating voltage of your
unit is identical with the voltage of your
local power supply. If voltage adaptation is
required, consult with qualified Sony
personnel.
• 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 get your fingers caught in
the adjuster.
• Do not spread a cloth or paper under the
unit.
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 unit 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.
Preventing internal heat build-up
The unit 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.
Cleaning
Before cleaning
Be sure to disconnect the AC power cord
from the AC outlet.
Cleaning the air filter
• Clean the air filter whenever you replace
the lamp.
• Refer to the "Cleaning the Air Filter" on
page 14 for the air filter cleaning.
Cleaning the lens
The lens surface is especially treated to
reduce reflection of light.
As incorrect maintenance may impair the
performance of the projector, take care with
respect to the following:
• 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.
• Wipe the lens gently with a soft cloth such
as a cleaning cloth or glass cleaning cloth.
• Stubborn stains may be removed with a
soft cloth such as a cleaning cloth or glass
cleaning cloth lightly dampened with
water.
• Never use solvent such as alcohol, benzene
or thinner, or acid, alkaline or abrasive
detergent, or chemical cleaning cloth, as
they will damage the lens surface.
Cleaning the cabinet
• Clean the cabinet gently with a soft dry
cloth. Stubborn stains may be removed
with a cloth lightly dampened with mild
detergent solution, followed by wiping
with a soft dry cloth.
• Use of alcohol, benzene, thinner or
insecticide may damage the finish of the
cabinet or remove the indications on the
cabinet. Do not use these chemicals.
