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 or set the MAIN 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, even if the unit itself has been turned
off.
On installation
•When the projector is mounted on the ceiling, the Sony PSS-70 Projector
Suspension Support must be used for installation. Read the installation
manual of the PSS-70 carefully, since the ceiling should be reinforced for
safety.
•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 (12 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.
•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.

Overview 9
Overview
•Fans are installed inside the projector to prevent internal heat build-up.
The fans produce a humming noise when the power is switched on, which
is normal. Should the noise sound abnormal, please consult qualified
Sony personnel.
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 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.
CRT burns
When a static picture of a VCR or a computer is displayed for more than
about an hour, a CRT burn may result. This means that an after-image
impression of the static picture remains on the screen even after the picture
has changed. If it is necessary to display the same static picture for more
than an hour, we recommend that you set the CONTR (contrast) control to
the lowest setting.
Also, when a picture of different size is displayed beyond a certain length
of time, an after-image impression of the frame of the smaller picture may
be burnt on the screen (such as displaying a 16:9 wide size picture on a 4:3
screen). To avoid this, we recommend that you use the same picture size
when possible. However, if it is necessary to use a different picture size,
set the CONTR (contrast) control and the BRT (brightness) control of the
smaller picture to the lowest setting possible. This will minimize the risk
of creating an after-image impression.
If the CRT burns, it must be replaced. In this case, refer to the warranty
provided with this unit. Consult your Sony dealer or Qualified Service
Personnel.
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.

Overview
Features
1) NTSC4.43 is the color system used when playing back a video recorded on NTSC on a NTSC4.43 system VCR.
..........................................................................................................................................................................................................
Multiscan projector
This projector accepts and automatically detects horizontal scanning
frequencies between 15 kHz and 110 kHz and vertical scanning
frequencies between 38 Hz and 150 Hz.
In addition to high-resolution pictures from computers, you can also
project pictures from teletext decoders, VCRs and video cameras.
High resolution and brightness
A newly developed 8-inch electromagnetic focus CRT, a hybrid Sony
HACC (High-resolution Aspherical and Color Corrected) lens and a wide-
range cathode/G1 dual-drive video output circuit are incorporated in the
projector to provide a sharp and bright high-quality picture with the high
resolution of 1700 ×1200 pixels and the high light output of 200 lumen.
High contrast
The adoption of the optical coupling technologies, double-focus lens
system and an anti-reflection coating gives a fine-detail and sharp picture
with improved contrast in corners and screen center.
Easy operation — remote commander, on-screen display
Adjustments such as input selection, picture control and centering
adjustment can be remotely controlled from both the front and rear of the
projector with the supplied remote commander. You can also use the
commander as a wired remote control by connecting it to the projector
with the supplied remote control cable.
Compatible with various color systems
NTSC, PAL, SECAM, NTSC4.431) or PAL-M color system can be selected
automatically or manually.
Flexible setup
You can project a 60- to 300-inch picture (120-inch standard) with this
projector. The projector can be set up on the floor or ceiling, for front or
rear projection to suit the installation location, surrounding illumination,
usage, etc.

Notes on wireless remote control operation
•Be sure that there is nothing to obstruct the infrared
beam between the remote commander and the
projector.
•The operation range is limited. The shorter the
distance between the remote commander and the
projector, the wider the angle within which the
remote commander can control the projector.
•The remote control detectors on the projector do not
operate when the remote commander is being used as
a wired remote control. If you wish to use the remote
commander as a wireless remote control, be sure to
remove the connecting cable from both the remote
