Resumen del manual
These are related to another group of environmental toxins, PCBs, 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 fearthat disturbances in foetus development may occur. TCO'95 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 nervoussystem and in higher doses, causes lead poisoning. TCO'95 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 computerdisplays. Cadmium damages the nervous system and is toxic in high doses. TCO'95 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 istoxic in high doses. TCO'95 requirement states that batteries may not contain more than 25 ppm (parts permillion) of mercury. It also demands that no mercury is present in any of the electrical or electronicscomponents 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'95 requirement: Neither CFCs nor HCFCs may be used during the manufacturing of the product or its packaging. Benutzerhandbuch 66 Information Regulatory • TCO'99-Ecological requirements for personal computers (TCO applied model only) 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 theenvironment 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 labelling of personal computers. The labelling scheme was developed asa joint effort by the TCO(The Swedish Confederation of Professional Employees), SvenskaNaturskyddsforeningen(The Swedish Society for Nature Conservation), Statens Energimyndighet(The Swedish National Energy Administration) and SEMKO AB. The requirements cover a wide range of issuse: environment, ergonomics, usability, reduction of electric and magnetic fields, energy consumption and electrical safety. Why do we have environmentally labelled computers? In many countries, environmental labelling has become an established method for encouraging theadaptation of goods and services to the environment. The main problem, as far as computers and otherelectronics equipment are concerned, is that environmentally harmful substances are used both in theproducts and during their manufacture. Since it is not so far possible to satisfactorily recycle the majority ofelectronics 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 importantfrom the viewpoints of both the work (internal) and natural (external) environments. Since all methods ofelectricity 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 runningcontinuously and thereby consumes a lot of energy. What does labelling involve? The environmental demands has been developed by Svenska Naturskyddsforeningen (The Swedish Societyfor 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 toreactivate the computer shall be reasonable for the user. Below you will find a brief summary of the environmental requirements met by this product.
