You have just purchased a TCO’95 approved and labelledproduct! Your choice has provided you with a productdeveloped for professional use. Your purchase has alsocontributed to reducing the burden on the environment andto the further development of environmentally-adaptedelectronic products.Why do we have environmentally labelled computers? In many countries, environmental labelling has become anestablished method for encouraging the adaptation ofgoods and services to the environment. The main problemas far as computers and other electronic equipment areconcerned is that environmentally harmful substances areused both in the products and during their manufacture.Since it has not been possible so far for the majority ofelectronic equipment to be recycled in a satisfactory way,most of these potentially damaging substances sooner orlater enter Nature.There are also other characteristics of a computer, such asenergy consumption levels, that are important from both theworking and natural environment viewpoints. Since alltypes of conventional electricity generation have a negativeeffect on the environment (acidic- and climatic-influencingemissions, radioactive waste, etc.), it is vital to conserveenergy. Electronic equipment in offices consumes asenormous amount of energy, since it is often routinely leftrunning continuously.What does the environmenal labelling involve?This product meets the requirements for the TCO’95 Regulatory InformationNOTICEThe regulations are applied only to the products with theID LABEL indicating specific requirements.NOTICEThe regulations are applied only to the products with theID LABEL indicating specific requirements.NOTICEThe regulations are applied only to the products with theID LABEL indicating specific requirements.
2Regulatory Information cont.NUTEKNaturskyddsföreningen Närings- och teknikutvecklingsverket SEMKOscheme, which provides for international environmentallabelling of personal computers. The labelling scheme wasdeveloped as a joint effort by the TCO (The SwedishConfederation of Professional Employees),Naturckyddsföreningen (The Swedish Society for NatureConservation), and NUTEK (The National Board forIndustrial and Technical Development in Sweden), andSEMKO AB (an international certification agency).The requirements cover a wide range of issues:environment, ergonomics, usability, emission of electricaland magnetic fields, energy consumption and electrical andfire safety.The environmental demands concern, among other things,restriction on the presence and use of heavy metals,brominated and chlorinated flame retardants, CFCs(freons), and chlorinated solvents. The product must beprepared for recycling, and the manufacturer is obliged tohave an environmental plan, which must be adhered to ineach country where the company implements itsoperational policy. The energy requirements include a demand that thecomputer and/or display, after a certain period of inactivity,shall reduce its power consumption to a lower level, in oneor more stages. The length of time to reactivate thecomputer shall be reasonable for the user.Labelled products must meet strict environmentaldemands, for example, in respect of the reduction of electricand magnetic fields, along with physical and visualergonomics and good usability.The following is a brief summary of the environmentalrequirements met by this product.

Up to 30% of the plastic in acomputer casing can consist of flame-retardant substances.These are related to another group of environmental toxins,PCBs, and are suspected of giving rise to similar harm,including reproductive damage in fish-eating birds andmammals. Flame retardants have been found in humanblood, and researchers fear that they can disturb fetusdevelopment. Bio-accumulative1TCO’95 demands require that plasticcomponents weighing more than 25 grams must notcontain flame retardants with organically bound chlorine orbromine.Lead can be found in picture tubes, display screens, solder,and capacitors. Lead damages the nervous system and inhigher doses causes lead poisoning. The relevant bio-accumulative TCO’95 requirement permits the inclusion oflead, as no replacement has yet been developed.Cadmium is present in rechargeable batteries and in thecolor-generating layers of certain computer displays.Cadmium damages the nervous system and is toxic in highdoses. The relevant bio-accumulative TCO’95 requirementstates that batteries may not contain more than 25 ppm(parts per million) of cadmium. The color-generating layersof display screens must not contain any cadmium.Mercury is sometimes found in batteries, relays andswitches. Mercury damages the nervous system and istoxic in high doses. The relevant bio-accumulative TCO’95requirement states that batteries may not contain more than 25 ppm of mercury and that no mercury is present in any ofthe electrical or electronic components concerned with thedisplay unit.CFCs (freons) are sometimes used for washing printedcircuit boards and in the manufacture of expanded foam forpackaging. CFCs break down ozone and thereby damagethe ozone layer in the atmosphere, causing increasedreception on Earth of ultra-violet light with consequentincreased risks of skin cancer (malignant melanoma). Therelevant TCO’95 requirement: Neither CFCs nor HCFCsmay be used during the manufacture of the product or itspackaging.1Bio-accumulative means that the substance accumulateswithin living organisms.Shipping PackageThe packaging material can be recycled, or you can save itto return the monitor to a service center for repair ordisposal.CFC Compounds in Distribution PackagingCushioning material used for shipping finished monitors arenot manufactured with nor do they contain any CFCcompounds.Design for Disassembly/RecyclingThese monitors have been designed for easy end-of-lifedisassembly and recycling. Fasteners are generally of thesame type for efficient disassembly. Components made ofdifferent materials can be easily separated and plasticshave been identified using intermational symbols to aid inrecycling.Monitor DisposalWARNINGIf you need to dispose of a monitor, ask a qualified servicerepresentative for the proper procedure. Improper disposalcould result in personal injury from implosion.
