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.
• Avoid using an extension cord with a low voltage
limited since it may cause the short-circuit and
physical incidents.
• To carry the projector, be sure to use the carrying
handle. Do not hold other parts of the projector,
especially the lens, nor catch your finger between the
handle, floor, and the projector.
• Do not catch your finger between the unit and
surface of the floor when moving the projector
installed on the floor.
• Be careful not to catch your finger in the cooling fan.
• Do not carry the projector with the cabinet on and
with its cover open.
On installation
• When the projector is mounted on the ceiling, the
Sony PSS-610 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
between the wall and the projector. Be aware that
room heat rises to the ceiling; check that the
temperature near the installation location is not
excessive.
• Install the projector on the floor or ceiling. Any other
installation causes a mulfunction such as color
irregularity or shortening lamp life.
• 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.
• Be sure to secure the cabinet cover firmly when
installing to the ceiling firmly.
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 / 1 key on
the control panel or on the Remote Commander, do
not disconnect the unit from the wall outlet while the
cooling fan is still running.
• Do not disconnect the AC power cord from the wall
outlet while the fan is still running.
Caution
The projector is equipped with ventilation holes
(intake) at the bottom and ventilation holes (exhaust)
at 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.
