Precautions
Precautions
On 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 Sony 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 from 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 (exhaust) — the air
coming out is hot.
• Be careful not to get your fingers caught in
the adjuster. The powered tilt adjuster of
this unit automatically extends when the
power is turned on, and is retracted
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 use the product with the filter
removed.
• Do not drop in at the exhaust outlet.
On illumination
• To obtain the best picture, the front of the
screen should not be exposed to direct
lighting or sunlight.
• 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.
On preventing internal heat build-
up
The unit is equipped with ventilation holes
(intake) at the bottom and ventilation holes
(exhaust) at the side. Do not block or place
anything near these holes, or internal heat
build-up may occur, causing picture
degradation or damage to the unit.
On cleaning
Before cleaning
Be sure to disconnect the AC power cord
from the AC outlet.
On cleaning the air filter
• Clean the air filter regularly.
• Refer to the “Cleaning the Air Filter” on
page 51 for the air filter cleaning.
On cleaning the lens cover
The lens cover 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 cover. To remove
dust on the lens, use a soft dry cloth. Do
not use a damp cloth, detergent solution, or
thinner.
• Wipe the lens cover 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 cover surface.
On 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
