ViewSonic VA503biTCO 信息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 established method for encouragingthe adaptation of goods and services to the environment. With the growing manufacture andusage of electronic equipment throughout the world, there is a recognized concern for thematerials and substances used by electronic products with regards to their eventual recyclingand disposal. By proper selection of these materials and substances, the impact on theenvironment can be minimized.There are also other characteristics of a computer, such as energy consumption levels, that areimportant from the viewpoints of both the work (internal) and natural (external) environments.Electronic equipment in offices is often left running continuously, resulting in unnecessaryconsumption of large amounts of energy and additional power generation. From the standpointof 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 internationaland environmental labelling of personal computers and/or displays. The labelling scheme wasdeveloped as a joint effort by the TCO (The Swedish Confederation of ProfessionalEmployees), 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 ofelectrical and magnetical fields, energy consumption and electrical safety.Ecological criteria impose restrictions on the presence and use of heavy metals, brominatedand chlorinated flame retardants, and other substances. The product must be prepared forrecycling and the manufacturing site(s) shall be certified according to ISO14001 or EMASregistered.Energy requirements include a demand that the system unit and/or display, after a certainperiod 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 thereduction of electrical and magnetical fields as well as work load and visual ergonomics.
