15" TFT LCD Color Monitor
Congratulations ! You have just purchased a TCO 99 approved and labelled
product! Your choice has provided you with a product developed for profes
sional 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 adaptation
of goods and services to the environment. The main problem, as far as computers and other electronics equip
ment 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 climate influencing emissions, ra
dioactive 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 99 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, emission of electrical and magnetic fields, energy con
sumption and electrical and fire safety. The environmental demands concern 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
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.

product. The complete environmental criteria document may be ordered from:

TCO 99 is a co operative project between TCO (The Swedish Confederation of Professional Employees), Na
turskyddsforeningen (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 wiring 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 flame
retardant substances. These are related to another group of environmental toxins, PWBs, which are suspected
to give rise to similar harm, including reproductive damage in fish eating birds and mammals, due to the
bioaccumulative processes. Flame retardants have been found in human blood and researchers fear that distur
bances in foetus development may occur.
TCO 99 demand requires that plastic components weighing more than 25 grams must not contain organically
bound chlorine and bromine.
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 99 requirement permits the inclusion of lead since no replacement has yet been developed.
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.
TCO 99 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 99 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.
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 light with consequent increased risks of skin cancer (malignant
melanoma).
The relevant TCO 99 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.
