Precautions
Precautions
• 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.
• Be careful not to catch your fingers by the
front feet (adjustable) when you adjust the
height of the unit. Do not push hard on the
top of the unit with the front feet
(adjustable) out.
• Avoid using an extension cord with a low
voltage limited since it may cause the
short-circuit and physical incidents.
• Do not catch your finger between the unit
and surface of the floor when moving the
projector installed on the floor.
• Do not move the projector when it is
turned on and the cabinet cover is open.
• 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.
• Never mount the projector on the ceiling
or move it by yourself. Be sure to consult
with qualified Sony personnel (charged).
• If the ventilation holes are blocked,
internal heat builds up, and it may cause a
fire or damage the unit. To allow adequate
air circulation and prevent internal heat
build-up, follow the items below:
• Leave space around the unit (page 6).
• Avoid using something to cover the
ventilation holes (exhaust/intake).
• Do not place the unit on surfaces such as
an original packing sheet, soft cloth,
papers, rugs, or scraps of paper. The
ventilation holes may take in such
materials.
• Do not place any object just in front of the
lens that may block the light during
projection. Heat from the light may
damage the object. Use the picture muting
function to cut off the picture.
On safety

6Precautions
• Do not use the Security bar for the purpose
of preventing theft for transporting or
installing the unit. If you lift the unit by the
Security bar or hang the unit by this bar, it
may cause the unit to fall and be damaged,
and may result in personal injury.
For dealers
• Be sure to secure the cabinet cover firmly
when installing to the ceiling firmly.
• When installing the unit, leave space
between any walls, etc. and the unit as
illustrated.
• Avoid using if the unit is tilted more than
15 degrees horizontally.
• Avoid using the unit in a location where
the temperature or humidity is very high,
or temperature is very low.
• Avoid installing the unit in a location
subject to direct cool or warm air from an
air-conditioner. Installing in such a
location may cause malfunction of the unit
due to moisture condensation or rise in
temperature.
• Avoid installing the unit in a location near
a heat or smoke sensor. Installing in such a
location may cause malfunction of the
sensor.
• Avoid installing the unit in a very dusty or
extremely smoky environment.
Otherwise, the air filter will become
obstructed, and this may cause a
malfunction of the unit or damage it.

Precautions
• When using the unit at an altitude of 1,500
m or higher, set “High Altitude Mode” to
“On” in the Installation menu. Failing to
set this mode when using the unit at high
altitudes could have adverse effects, such
as reducing the reliability of certain
components.
• Set “Installation Attitude” on the
Installation menu correctly to suit to the
Installation angle. Continuing to use the
wrong setting may affect component
reliability.
• Be sure to disconnect the AC power cord
from the AC outlet before cleaning.
• If you rub on the unit with a stained cloth,
the cabinet may be scratched.
• If the unit is exposed to volatile materials
such as insecticide, or the unit is in contact
with a rubber or vinyl resin product for a
long period of time, the unit may
deteriorate or the coating may come off.
• Do not touch the lens with bare hands.
• On cleaning the lens surface:
Wipe the lens gently with a soft cloth, such
as a glass cleaning cloth. Stubborn stains
may be removed with a soft cloth lightly
dampened with water. Never use solvent
such as alcohol, benzene or thinner, or
acid, alkaline or abrasive detergent, or a
chemical cleaning cloth.
• On cleaning the cabinet:
Clean the cabinet gently with a soft cloth.
Stubborn stains may be removed with a
soft cloth lightly dampened with mild
detergent solution and wrung, followed by
wiping with a soft dry cloth. Never use
solvent such as alcohol, benzene or
thinner, or acid, alkaline or abrasive
detergent, or a chemical cleaning cloth.
To obtain the best picture, the front of the
screen should not be exposed to direct
lighting or sunlight.
The LCD projector is manufactured using
high-precision technology. You may,
however, see tiny black points and/or bright
points (red, blue, or green) that continuously
appear on the LCD projector. This is a
normal result of the manufacturing process
and does not indicate a malfunction.
Also, when you use multiple LCD projectors
to project onto a screen, even if they are of
the same model, the color reproduction
among projectors may vary, since color
balance may be set differently from one
projector to the next.
When using a screen with an uneven surface,
stripes pattern may rarely appear on the
screen depending on the distance between
the screen and the unit or the zooming
magnifications. This is not a malfunction of
the unit.
Since the projector is equipped with fans
inside to prevent internal temperature from
rising, there may be some noise. This is a
normal result of the manufacturing process
and does not indicate a malfunction. If,
however, in a case of abnormal noise,
consult with qualified Sony personnel.
The lamp used as a light source contains
mercury that has high internal pressure. A
high-pressure mercury lamp has the
following characteristics:
• Brightness of the lamp will be lowered as
the elapse of time used.
• The lamp may break with a loud noise as a
result of shock, damage, or deterioration
caused by the elapse of time. The lamp
may become unlit and may burn out.
• The lamp life varies with individual
differences or usage conditions of each
lamp. Therefore, it may break or will not

light even before the specified
replacement time.
• It may possibly break after the
replacement time has elapsed. Replace the
lamp with a new one as soon as possible if
a message displayed on the projected
image, even if the lamp normally lights.
This unit is precision equipment. When
carrying the unit, do not subject the unit to
shocks, or fall. It may damage the unit.

About remote commander operation
• Direct the remote commander toward the
remote control detector.
• The shorter the distance between the
remote commander and the projector is,
the wider the angle within which the
remote commander can control the
projector becomes.
• Make sure that nothing obstructs the
infrared beam between the remote
commander and the remote control
detector on the projector.

BPreparation
Connecting the Projector
• Make sure all the equipment is powered off when connecting the projector.
• Use the proper cables for each connection.
