TCO'95

MultiSync LCD1700NX Black Model
Congratulations! You have just purchased a TCO'95 approved and labeled
product! Your choice has provided you with a product developed for pro-
fessional 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 encourag-
ing 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 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) environ-
ments. Since all methods of conventional electricity generation have a negative effect on the
environment (acidic and climate-influencing 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, er gonomics, usability, emission
of electrical and magnetic fields, energy consumption 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 com-
puter 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.
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).
