Precautions
On safety
• Operate the unit on 200 – 240 V AC, 50/60 Hz.
• 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 or set the
POWER switch to OFF 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 and the main POWER switch is set to ON.
• 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.
• Have at least four people carry and handle the
projector, to avoid accidents or injury.
• Avoid using an extension cord with a low voltage
limit, as it may cause short-circuiting and physical
injury.
• To carry the projector, be sure to use the carrying
handles. 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 by holding the cover of the
cabinet.
• Do not carry the projector with the cabinet on and
with its cover open.
On 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 80 cm (31
1
/
2
inches) 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 hang it from the
ceiling. Any other installation causes a malfunction
such as color irregularity or a shorten 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.
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 15 minutes while the ON indicator flashes in
green.
Caution
The projector is equipped with ventilation holes
(intake) at the front and right/left side, and ventilation
holes (exhaust) at the left 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.
• Have the lamp filters and air filter inside the unit
cleaned regularly by qualified Sony personnel. If the
filters are clogged, internal heat may build up and the
power may be turned off automatically.
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.

Features
Features
High brightness, high picture quality
• High brightness
The combination of a 2 kW arc Xenon lamp and Digital
Light Processing
TM
(DLP
TM
), a Texas Instruments
technology, provides superb light output of 10,000
ANSI lumen while assuring excellent uniformity on the
entire screen.
• High resolution
Thanks to use of three SXGA-resolution Digital
Micromirror Device
TM
(DMD
TM
) panels with
approximately 1,300,000 pixels, the projector can
project the sharp picture with the resolution of 1280
×
1024 pixels.
• DRC (Digital Reality Creation)
The DRC technology allows you to obtain a finer, more
detailed picture with four-times higher density than the
conventional video picture.
• 2-3 Pull-Down technology
The 2-3 Pull-Down technology allows you to obtain a
smooth picture movement when playing back movies
or other video sources on film. To activate the 2-3
Pull-Down technology, set FILM to ON in the
PICTURE CTRL menu. (Effective for the NTSC
3.58/4.43
,
PAL-M, 15 k RGB (60 Hz) and 525/60 signals only.)
Accepts various input signals
This projector has a built-in high performance scan
converter which converts the input signals to display
the 15 k RGB, DTV, HDTV, VGA, SVGA, XGA,
SXGA and UXGA (fV = up to 75 Hz) signals as well as
the composite video
1)
, S video
1)
and component signals.
The projector accepts a wide range of HDTV/DTV
signals as shown in the chart below.
Digital HDTV signals are also acceptable when the
optional IFB-LE100 interface board is installed.
System expandability and versatility
The projector has RS-232C/422A/PJ COM interface
connectors for communication.
By combining the interface boards and signal interface
switcher (not supplied), the projection systems can be
greatly expanded. The projector also has the group and
device index functions for using multiple projectors in
one system.
Easy and flexible setup
• Sony’s original APA (Auto Pixel Alignment)
function
You can obtain the clearest picture automatically by
simply pressing the APA key when the signal is input
from a computer.
• Easy setup with external equipment
This projector has 49 preset data for input signals in
the memory. You can get a clear picture on the screen
simply by connecting equipment and pressing the APA
key. (For the signals that are not preset, adjustment
may be necessary to get a clear picture.)
• Flexible setup
The lens shift function allows you to install the
projector in a wide range of locations, without
worrying about keystone distortion (the picture going
out of square). The power focus and power zoom
functions also let you change the size of the projection
screen without having to move the projector.
