Congratulations!
You have iust purchased a TCO’99 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.
This product meets the requirements for the TCO’99 scheme which provides for an
international environmental and quality labelling of personal computers. The labelling
scheme was developed as a joint effort by the Too (The Swedish Confederation of
Professional Employees), Svenska Naturskyddsforeningen (The Swedish Society for
Nature Conservation), Statens Energimyndighet (The Swedish National Energy
Administration) and SEMKO AB.
The requirements cover a wide range of issues: environment, ergonomics, usability,
reduction of electric and magnetic fields, energy consumption and electrical safety.
Why do we have envlronmentally labelled computers?
in many countries, environmental labelling has become an established method for
encouraging the adaptation 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 satisfactorily recycle the majority of
electronics equipment, 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 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 continuously and
thereby consumes a lot of energy.
Environmental Labelllng ot Personal Computers
What does the environmenal labelling involve?
The environmental demands has been developed by Svenska Naturskyddstoreningen
(The Swedish Society for Nature Conservation). These demands impose restrictions on the
presence and use of heavy metals, brominated and chlorinated flame retardants, CFCs
(freons) and chlorinated solvents, among other things. The product must be prepared for
recycling and the manufacturer is obliged 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 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.
Below you will find a brief summary of the environmental requirements met by this product.
The complete environmental criteria document may be ordered from:

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 retardants
contain bromine or chloride, and those flame retardants are chemically related to another
group of environmental toxins, PCBs. Both the flame retardants containing bromine or
chloride and the PCBs are suspected 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 weighing more than 25
grams must not contain flame retardants with organically bound bromine or chlorine. Flame
retardants are allowed in the printed circuit boards since no substitutes are available.
iv
Environmental Labelling of Personal Computers
“h—
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 components must not contain
any cadmium.
Mercury"
Mercury is sometimes found in batteries, relays and switches. It damages the nervous
system and is toxic in high doses. The relevant TCO’99 requirement states that
batteries may not contain any mercury. It also demands that mercury is not present in
any of the electrical or electronics components associated with the labelled unit. There
is however one exception Mercury is, for the time being, permitted in the back light
system of flat panel monitors as there today is no commercially available alternative.
TCO aims on removing this exception when a mercury free alternative is available.
CFCs (freons)
The relevant TCO‘99 requirement states that neither CFCs nor HCFCs may be used
during the 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. causing increased reception 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, causes lead poisoning. The relevant
TCO'99 requirement permits the inclusion of lead since no replacement has yet been
developed.

User Modes
————______—___
Modes 17-26 are empty and can accept new video data. It the monitor detects a
new video mode that has not been present before or is not one of the preset
modes, it stores the new mode automatically in one of the empty modes starting
with mode 17.
If you use the 4 blank modes and still have more new video modes. the monitor
replaces the information in the user modes starting with mode 17.
Recalling Display Modes
“—
When your monitor detects a mode it has seen belore, it automatically recalls the
image settings you may have made the last time you used that mode.
You may, however, manually force a recall of each at the 16 preset modes by
pressing the Recall button. All preset modes are automatically recalled as the
monitor senses the incoming signal.
The ability to recall the preset modes is dependent on the signal coming from
your PC's video card or system. If this signal does not match any of the factory
modes, the monitor automatically sets itself to display the image.
