subject to direct sunlight

• in a place subject to severe temperature changes

• in a place subject to mechanical vibration or shock

• on an unstable surface

• near equipment which generates magnetism, such as a
transformer or high voltage power lines

• near or on an electrically charged metal surface

Maintenance

• Clean the screen with a soft cloth. If you use a glass cleaning
liquid, do not use any type of cleaner containing an anti-static
solution or similar additive as this may scratch the screen’s

Troubleshooting

This section may help you find the cause of a problem so you can

solve the problem yourself.

When the monitor receives an input signal, it automatically

matches the signal to one of the 26 factory preset modes stored in
the monitor’s memory to provide a high quality picture at the
center of the screen. (See the Appendix for a list of the factory
preset modes.) For input signals that do not match one of the
factory preset modes, the digital Multiscan technology of this
monitor ensures that a clear picture appears on the screen for any
timing in the monitor’s frequency range (horizontal: 30-96 kHz,

vertical: 48-120 Hz). If the picture is adjusted, the adjustment
data is stored as a user mode and automatically recalled whenever
the same input signal is received.

Note for Windows users

For Windows users, check your gr^hic video board manual or
the utility program which comes with your graphic video board
and select the highest available refresh rate to maximize monitor

performance.

Power saving function

This monitor meets the power-saving guidelines set by VESA,
ENERGY STAR, and NUTEK. If the monitor is connected to a

computer or graphic video board that is DPMS (Display Power

The lines you may be seeing on your screen are normal for the

Trinitron monitor and are not a malfunction. These are shadows
from the damper wires that stabilize the aperture grille, and are
most noticeable when the screen’s background is light (usually

white).

The aperture grille is the essential element that makes a Trinitron

picture tube unique by allowing more light to reach the screen,
resulting in a brighter, more detailed picture.

TCO’95 Eco-document

■ Congratulations!

You have just purchased a TCO’95 approved and labelled
product! Your choice has provided you with a product developed
for professional use. Your purchase has also contributed to
reducing the burden on the environment and also, to the further
development of environmentally adapted electronics products.

■ Why do we have environmentally labelled

computers?

In many countries, environmental labelling has become an
established method for encouraging the ad^tadon of goods and
services to the environment. The main problem, as far as
computers and other electronics equipment are concerned, is that
environmentally harmful substances are used both in the products
and during the manufacturing. Since it has not been possible for
the majority of electronics equipment to be recycled in a

satisfactory way, most of these potentially damaging substances
sooner or later enter Nature.
There are also other characteristics of a computer, such as energy
consumption levels, that are important from the viewpoints of
both the work (internal) and natural (external) environments.
Since all methods of conventional electricity generation have a
negative effect on the environment (acidic and climate­influencing emissions, radioactive waste, etc.), it is vital to
conserve energy. Electronics equipment in offices consume an
enormous amount of energy since they are often left running
continuously.

■ What does labelling involve?

This product meets the requirements for the TCO’95 scheme

which provides for international and environmental labelling of
personal computers. The labelling scheme was developed as a
joint effort by the TCO (The Swedish Confederation of

Professional Employees), Naturskyddsforeningen (The Swedish

Society for Nature Conservation) and NUTEK (The National

Board for Industrial and Technical Development in Sweden).

The requirements cover a wide range of issues: environment,

ergonomics, usability, enussion of electrical and magnetic fields,

energy consumption and electrical and fire safety.

(continued)

I

Sony Corporation Printed In U.S.A.

The environmental demands concern restrictions on the presence
and use of heavy metals, brominated and chlorinated flame

retardants, CFCs (fréons) and chlorinated solvents, among other
things. The product must be prepared for recycling and the
manufacturer is obliged to have an environmental plan which
must be adhered to in each country where the company
implements its operational policy.
The energy requirements include a demand that the computer and/
or display, after a certain period of inactivity, shall reduce its

power consumption to a lower level in one or more stages. The
length of time to reactivate the computer shall be reasonable for
the user.

Labelled products must meet strict environmental demands, for
example, in respect of the reduction of electric and magnetic

fields, physical and visual ergonomics and good usability.

Cadmium“

Cadmium is present in rechargeable batteries and in the
colourgenerating layers of certain computer displays. Cadmium

damages the nervous system and is toxic in high doses.

TCO’95 requirement states that batteries may not contain more
than 25 ppm (parts per million) of cadmium. The colour
generating layers of display screens must not contain any
cadmium.

Mercury“

Mercury is sometimes found in batteries, relays and switches.
Mercury damages the nervous system and is toxic in high doses.
TCO’95 requirement states that batteries may not contain more
than 25 ppm (parts per million) of mercury. It also demands that
no mercury is present in any of the electrical or electronics
components concerned with the display unit.

On this page, you will find a brief summary of the environmental
requirements met by this product. The complete environmental
criteria document may be ordered from:

TCO’95 is a co-operative project between TCO (The Swedish
Confederation of Professional Employees),
Naturskyddsforeningen (The Swedish Society for Nature

Conservation) and NUTEK (The National Board for Industrial
and Technical Development in Sweden).

■ Environmental Requirements Brominated flame retardants

Brominated flame retardants are present in printed circuit boards,

cables, wires, casings and housings. In turn, they delay the spread
of fire. Up to thirty percent of the plastic in a computer casing can
consist of ñame retardant substances. These are related to another
group of environmental toxins, PCBs, which are suspected to give
rise to similar harm, including reproductive damage in fisheating
birds and mammals, due to the bio-accumulative* processes.
Flame retardants have been found in human blood and researchers

fear that disturbances in foetus development may occur.
TCO’95 demand requires that plastic components weighing more
than 25 grams must not contain organically bound chlorine and
bromine.

CFCs (freons)

CFCs (freons) are sometimes used for washing printed circuit

boards and in the manufacturing of expanded foam for packaging.

CFCs break down ozone and thereby damage the ozone layer in

the stratosphere, causing increased reception on Earth of

ultraviolet Ught with consequent increased risks of skin cancer

(maUgnant melanoma).

The relevant TCO’95 requirement: Neither CFCs nor HCFCs

may be used during the manufacturing of the product or its

packaging.

* Bio-accumulative is defined as substances which accumulate

within living organisms

*♦ Lead, Cadmium and Mercury are heavy metals which are Bio-

accumulative.

Lead“

Lead can be found in picture tubes, display screens, solders and
capacitors. Lead damages the nervous system and in higher doses,
causes lead poisoning.
TCO’95 requirement permits the inclusion of lead since no
replacement has yet been developed.
