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 — the air
coming out is hot.
On installation
• When the projector is mounted on the ceiling, the Sony PSS-2000
Projector Suspension Support must be used for installation.
• Allow adequate air circulation to prevent internal heat build-up. Do not
place the unit on surfaces (rugs, blankets, etc.) or near materials (curtains,
draperies) that may block the ventilation holes. Leave space of more than
30 cm (11 7 /
room heat rises to the ceiling; check that the temperature near the
installation location is not excessive.
• Do not install the unit in a location near heat sources such as radiators or
air ducts, or in a place subject to direct sunlight, excessive dust or
humidity, mechanical vibration or shock.
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 turning off the power, the cooling fan runs for about six minutes
while the ON indicator flashes in green. The indicator flashes quickly for
30 seconds. During that time, you will not be able to turn the power back
on with the ON key.
Caution
The projector is equipped with ventilation holes (intake) at the bottom/
front side and ventilation holes (exhaust) at the left/right side.
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 air filter in every 100 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.
