• Check that the operating voltage of your unit is identical with the voltage
of your local power supply. If voltage adaptation is required, consult
qualified service personnel.
• Should any liquid or solid object fall into the cabinet, unplug the unit and
have it checked by qualified service personnel before operating it further.
• Unplug the unit from the wall outlet or set the BREAKER ON/OFF
switch to OFF if you do not use the unit 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.
• When the projector is mounted on the ceiling, the Sony PSS-70 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
7
30 cm (11 / inches) between the wall and the projector. Be aware that
8
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.
• To avoid moisture condensation, do not install the unit in a location
where the temperature may rise rapidly.
Caution
The projector is equipped with ventilation holes (intake) on the front and
on the sides, and ventilation holes (exhaust) on the rear. Do not block these
holes. Otherwise, internal heat build-up may occur, causing picture
degradation or damage to the projector.
• To obtain the best picture, do not expose the front of the screen 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, we recommended that the carpet and wall paper be changed to a
dark color.
