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 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.
• When the projector is mounted on the ceiling, the Sony PSS-600
Projector Suspension Support must be used for installation.
• Be careful not to catch your fingers by the adjusters when you lift up the
projector. Do not push hard on the top of the projector with the adjusters
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 / u 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) at the bottom and
ventilation holes (exhaust) on the front. 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 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.
