Precautions
On safety
• Operate the unit on 200 – 240 V AC, 50/60 Hz (SRXT110), or 100 – 240 V AC, 50/60 Hz (SRX-T105).
• Should any liquid or solid object fall into the cabinet,
unplug the unit and have it checked by your Sony dealer
before operating it further.
• Unplug the unit from the wall outlet or set the power
switch to the lower position 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 power switch is set to the upper position.
• 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.
• Since an intense light has come out of this projector from
the front, do not stand on the front of a projector for a
long time.
• Should the lamp explode, it is dangerous to be near the
ventilation holes for exhaust. Keep at least 2 m (approx.
6.6 feet) away from the projector’s ventilation holes for
exhaust.

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 100 cm (39

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.
Chapter 1 Overview
• 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.
For maximum protection, repack your unit as it was
originally packed at the factory.
On “stuck” pixels on a LCD screen
The LCD panel fitted to this unit is manufactured with high
precision technology. Thus a very small proportion of
pixels may be “stuck”, either always off (black), always on
(red, green, or blue), or flashing. In addition, over a long
period of use, because of the physical characteristics of the
liquid crystal display, such “stuck” pixels may appear
spontaneously. These problems are not a malfunction.
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
10 minutes while the STATUS LAMP indicator flashes
green.
Caution
The projector is equipped with ventilation holes (intake) at
the front, upper side and right side, and ventilation holes
(exhaust) at the rear and upper 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 prohibiting continuous lighting
Continuously lighting the Xenon lamp for 24 hours will
reduce approximately half of its lamp life. Be sure to off
the lamp for an hour or more after continuously lighting for
24 hours.
To light the lamp continuously for 24 hours, it is
recommended to use the lamps alternately. To use the
lamps alternately, select “User-Defined” in “Single” (page
31) under “LAMP SELECT” in the INSTALLATION
window and set the time.
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.
On repacking
Save the original shipping carton and packing material;
they will come in handy if you ever have to ship your unit.

Precautions
Features
High Brightness, High Picture Quality
High brightness
The SRX-T110 uses two 2 kW Xenon lamps as a light
source, and the SRX-T105 uses two 1 kW Xenon lamps.
These compact-size Xenon lamps provide high brightness
of 11,000 lumens for the SRX-T110 and 5,500 lumens for
the SRX-T105, assuring excellent uniformity on the entire
screen.
High resolution
Sony’s new, unique three SXRD™ (Silicon X-tal
Reflective Display) panels with about 8,850,000 pixels
realizes a high-resolution of 4096 × 2160 dots. The
resolution corresponds to four times that of an HDTV
image.
Multi-screen mode
The high resolution of the projector enables single-, dualand quad-mode projection in which full HD images can be
displayed even in each of two or four divided screens.
Images from different input sources can be displayed in
these divided screens simultaneously.
High contrast ratio
The combination of the SXRD imaging devices and 3PBS
optical devices offers a high contrast ratio of 2500:1.
Gamma correction circuit
You can select a gamma value from 1.80 to 2.59 in 0.01
steps according to the signal input. (The values of 2.2 and
2.6 are fixed.) This allows projection of an image with
optimum brightness. (Only three types of gamma
correction circuit, 1.8, 2.2 and 2.6, may be selectable
according to the optional input board.)
Flexible and Reliable System
Dual lamp system
The projector adopts a dual lamp system for versatility of
use. You can select dual-lamp or single-lamp mode, and
can reduce each lamp’s power output. These modes allow
you to save power and increase lamp life.
Also, if one bulb burns out, the other keeps projecting
images.
Versatile Setup
Various signal input
The projector is equipped with an RS232C connector and
ETHERNET connector for communication. For signal
inputs, the projector has four slots to which the optional
analog input boards, HD-SDI input boards and DVI-D
interface boards can be attached according to your
requirement.
Optional lens
Optional zoom lenses are available depending on the
projection distance you are setting up. The lens shift
function of this projector enables easy setup.
When the optional zoom lens equipped with zoom/focus
memory function is installed, you can register the zoom
and focus settings adjusted to fit the desired screen size.
Registration of the settings adjusted for screen sizes of
aspect ratio of 4:3 and 16:9 allows you to switch between
them easily with the buttons in the window of the SRX
Controller.
Chapter 1 Overview
Color space feature
The projector supports four standards of color tonal
reproduction range, sRGB(ITU-R BT.709), DCDM,
Adobe RGB and CIE XYZ, allowing you to obtain an
image with precise color reproduction according to the
input sources.
Squeeze function
A squeezed signal with a 4:3 aspect ratio is stretched
horizontally to fit a 16:9 screen, and a signal with a 16:9
aspect ratio is stretched horizontally to fit a 2.39:1 screen.
This function is available only for projection in singlescreen mode and may not work depending on the signal
type input.

Chapter 2 Preparations
The projector is equipped with ventilation holes for intake
and exhaust to prevent internal heat build-up. Do not place
the projector in a place where the ventilation holes may be
blocked.
Situation that may block the ventilation
holes for exhaust
If you put something beside the ventilation holes for
exhaust on the side or rear of the projector, the exhaust
may be inhaled into the projector through the ventilation
holes for intake, causing internal heat build-up and thereby
A sudden change of temperature may produce moisture
condensation, causing damage to the projector. Take care
with heaters or air-conditioners.
