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

Congratulations!

You have just purchased a TCO’99 approved and labelled
product! Your cho ice has provided you wi th a product
developed for professional u se. Your pur chase 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 met hod for encour aging the adap tation 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 their manufacture.
Since it is not so far possible to satisfa ctor ily recycle the
majority of electronics equipment, most of these potentially
damaging substances sooner or later enter natu re.

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 electricity generation
have a negative effect on the environment (e.g. acidic and
climate-influencing emissions, radioactive waste), it is vital
to save energy. Electronics equipment in offices is often left
running continuousl y and thereby consumes a lot of energy.

What does labelling involve?

This product meets the requirements for the TCO’99 scheme
which provides for international and environmental label ling
of personal computers. The labelling scheme was developed
as a joint effort by the TCO (The Swedish Confederation of
Professional Employees), Svenska Naturskyddsforeningen
(The Swedish Societ y for Nature Cons ervation) and Staten s
Energimyndighet (The Swedish National Energy
Administration).

Approval requirements cover a wide range of issues:
environment, ergonomics, usability, emission of electric
and magnetic fields, energy consumption and electrical
and fire safety.

The environmental demands impose restrictions on the
presence and use of he avy metals, brominated and
chlorinated flame retardants , CFCs (freons) and chlorinated
solvents, among other things. The product must be prepared
for recycling and the manufact urer is oblige d to have an
environmental policy 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 i ts po wer cons ump tio n to a lo wer leve l in o ne
or more stages. The length of time to reactivate the computer
shall be reasonable for the user.
Labelled products must meet strict envi ronmental demands,
for example, in respect of the reduction of electric and
magnetic fields, physical and visual ergonomics and good
usability.

Environmental requirements

Flame retardants

Flame retardants are present in printed circuit boards,
cables, wires, casings and housings. Their purpose is to
prevent, or at least to delay the spread of fire. Up to 30% of
the plastic in a computer casing can consist of flame
retardant substances. Most flame retar dants contain
bromine or chloride, and those flame retardants are
chemically related to ano ther group of environmenta l toxins,
PCBs. Both the flame retardants containing bromine or
chloride and the PCBs are suspecte d of giving rise to
severe health effects, including reproductive damage in
fish-eating 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.
The relevant TCO’99 demand requires that plastic
components weig hing more than 25 gram s must not contai n
flame retardants with org anically bound bro mine or chlorine.
Flame retardants are allowed in the printed circuit boards
since no substitutes are available.

Cadmium

**

Cadmium is present in rechargeable batteries and in the
colour-generating layers of certain computer displays.
Cadmium damages the nervous system and is toxic in high
doses. The relevant TCO’99 requirement states that
batteries, the colour-generating layers of display screens
and the electrical or electronics compo nents must not
contain any cadmium.

Mercury

**

Mercury is sometimes found in batterie s, relays and
switches. It damages the nervous syst em and is toxic in
high doses. The relevant TCO’99 requirement states that
batteries may no t cont ain any merc ury. It also demand s
that mercury is not present in any of the electrical or
electronics components associated with the labelled unit.

CFCs (freons)

The relevant TCO’99 requirement states that neither CFCs
nor HCFCs may be used during th e manufacture and
assembly of the product. CFCs (freons) are sometimes
used for washing printed circuit boards. CFCs break down
ozone and thereby damage the ozone layer in the
stratosphere, cau sing increased recepti on on earth of
ultraviolet light with e.g. increased risks of skin cancer
(malignant melanoma) as a consequence.

**

Lead

Lead can be found in picture tubes, display screens,
solders and capacitors. Lead damages the nervous system
and in higher doses, caus es le ad po iso ning. The relevant
TCO´99 requirement permits the inclusion of lead since no
replacement has yet been developed.

Bio-accumulative is defined as substances which
accumulate within living organisms

**

Lead, Cadmium and Mercury ar e heavy metal s which
are Bio-accumulative.

1.2 Internal Preset Memory Capability

1.5 Location Considerations

To minimize adjustment needs, the factory has preset
popular display standards into the monitor, as shown in
Table 1. If any of these display standards are detected, the
picture size and position are automatically adjusted. All of
the factory presets may be overwritten by adjusting the user
controls. This monitor is capable of automatically storing up
to 16 additional display standards. The new display infor­mation must differ from any of the existing display stan­dards by at least 1kHz for the horizontal scan frequency or
5Hz for the vertical scan frequency or the sync signal
polarities must be different.
