Congratulations!You have just purchased a TCO'99 approved and labelled product!Your choice has provided you with a product developed forprofessional use. Your purchase has also contributed to reducing theburden on the environment and also to the further development ofenvironmentally adapted electronics products.Why do we have environmentally labelled computers?In many countries, environmental labelling has become an establishedmethod for encouraging the adaptation of goods and services to theenvironment. The main problem, as far as computers and otherelectronics equipment are concerned, is that environmentally harmfulsubstances are used both in the products and during their manufacture.Since it is not so far possible to satisfactorily recycle the majority ofelectronics equipment, most of these potentially damaging substancessooner or later enter nature.There are also other characteristics of a computer, such as energyconsumption levels, that are important from the viewpoints of both thework (internal) and natural (external) environments. Since all methodsof electricity generation have a negative effect on the environment(e.g. acidic and climate-influencing emissions, radioactive waste), it isvital to save energy. Electronics equipment in offices is often leftrunning continuously and thereby consumes a lot of energy.What does labelling involve?This product meets the requirements for the TCO'99 scheme, whichprovides for international and environmental labelling of personalPage1-2 stands forTCO’99 model only.Please see back labelfor model distinction.
computers. The labelling scheme was developed as a joint effort bythe TCO (The Swedish Confederation of Professional Employees),Svenska Naturskyddsforeningen (The Swedish Society for NatureConservation) and Statens Energimyndighet (The Swedish NationalEnergy Administration).Approval requirements cover a wide range of issues: environment,ergonomics, usability, emission of electric and magnetic fields, energyconsumption and electrical and fire safety.The environmental demands impose restrictions on the presence anduse of heavy metals, brominated and chlorinated flame retardants,CFCs (freons) and chlorinated solvents, among other things. Theproduct must be prepared for recycling and the manufacturer isobliged to have an environmental policy which must be adhered to ineach country where the company implements its operational policy.The energy requirements include a demand that the computer and/ordisplay, after a certain period of inactivity, shall reduce its powerconsumption to a lower level in one or more stages. The length of timeto reactivate the computer shall be reasonable for the user.Labelled products must meet strict environmental demands, forexample, in respect of the reduction of electric and magnetic fields,physical and visual ergonomics and good usability.On the Back page of this folder, you will find a brief summary of theenvironmental requirements met by this product.

TCO DevelopmentSE-114 94 Stockholm, SwedenFax: +46 8 782 92 07Email (Internet): development@tco.seCurrent information regarding TCO'99 approved and labelledproducts may also be obtained via the Internet, using the address:http://www.tco-info.com/Environmental requirementsFlame retardantsFlame retardants are present in printed circuit boards, cables, wires,casings and housings. Their purpose is to prevent, or at least to delaythe spread of fire. Up to 30% of the plastic in a computer casing canconsist of flame retardant substances. Most flame retardants containbromine or chloride, and those flame retardants are chemically relatedto another group of environmental toxins, PCBs. Both the flameretardants containing bromine or chloride and the PCBs are suspectedof giving rise to severe health effects, including reproductive damagein fish-eating birds and mammals, due to the bio-accumulative*processes. Flame retardants have been found in human blood andresearchers fear that disturbances in foetus development may occur.The relevant TCO'99 demand requires that plastic componentsweighing more than 25 grams must not contain flame retardants withorganically bound bromine or chlorine. Flame retardants are allowedin the printed circuit boards since no substitutes are available.CadmiumCadmium is present in rechargeable batteries and in the colour-generating layers of certain computer displays. Cadmium damages thenervous system and is toxic in high doses. The relevant TCO'99 * Bio-accumulative is defined as substances which accumulate within livingorganisms
requirement states that batteries, the color-generating layers of displayscreens and the electrical or electronics components must not containany cadmium.MercuryMercury is sometimes found in batteries, relays and switches. Itdamages the nervous system and is toxic in high doses. The relevantTCO'99 requirement states that batteries may not contain any mercury.It also demands that mercury is not present in any of the electrical orelectronics components associated with the labelled unit.CFCs (freons)The relevant TCO'99 requirement states that neither CFCs nor HCFCsmay 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 thestratosphere, causing increased reception on earth of ultraviolet lightwith e.g. increased risks of skin cancer (malignant melanoma) as aconsequence.Lead**Lead can be found in picture tubes, display screens, solders andcapacitors. Lead damages the nervous system and in higher doses,causes lead poisoning. The relevant TCO´99 requirement permits theinclusion of lead since no replacement has yet been developed. ** Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.
