TCO'99 - LCD174WXM
Congratulations!
You have just 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.
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. With the growing manufacture
and usage of electronic equipment throughout the world, there is a recognized concern
for the materials and substances used by electronic products with regards to their eventual
recycling and disposal. By proper selection of these materials and substances, the impact
on the environment can be minimized.
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. Electronic equipment in offi ces is often left running continuously, resulting in
unnecessary consumption of large amounts of energy and additional power generation. From
the standpoint of carbon dioxide emissions alone, it is vital to save energy.
What does labelling involve?
The product meets the requirements for the TCO'99 scheme which provides for international
and environmental labelling of personal computers and/or displays. The labelling scheme was
developed as a joint effort by the TCO (The Swedish Confederation of Professional Employees),
Svenska Naturskyddsforeningen (The Swedish Society for Nature Conservation) and Statens
Energimyndighet (The Swedish National Energy Administration).
Approval requirements cover a wide range of issues: ecology, ergonomics, emission of electrical
and magnetical fi elds, energy consumption and electrical safety.
Ecological criteria impose restrictions on the presence and use of heavy metals, brominated and
chlorinated fl ame retardants, and other substances. The product must be prepared for recycling
and the manufacturing site(s) shall be certifi ed according to ISO14001 or EMAS registered.
Energy requirements include a demand that the system unit 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 system unit shall be reasonable for the user.
Labelled products must meet strict environmental demands, for example, in respect of the reduction
of electrical and magnetical fi elds as well as work load and visual ergonomics.
