Nevertheless, the display may have cosmetic imperfections that appear as small bright or dark spots. This is common to all LCD displays used in products supplied by all vendors and is not specific to the HP D5063 LCD. These imperfections are caused by one or more defective pixels or sub-pixels. • A pixel consists of one red, one green, and one blue sub-pixel. • A defective whole pixel is always on (a bright spot on a dark background), or it is always off (a dark spot on a bright background). The first is the more visible of the two. • A defective sub-pixel (dot defect) is less visible than a defective whole pixel and is small and only visible on a specific background. The HP D5063 display does not have more than: • 10 total sub-pixel defects. • 5 defective red sub-pixels. • 5 defective green sub-pixels. • 5 defective blue sub-pixels. • No more than four pairs of adjacent defective sub-pixels i.e. no fully defective pixel. To locate defective pixels, the monitor should be viewed under normal operating conditions, in normal operating mode at a supported resolution and refresh rate, from a distance of approximately 50 cm (16 in.).

Your purchase has also contributed to reducing the burden on the environment and 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 labeling of personal computers.

English 51 hp L1520/hp L1720/hp L1820 LCD Monitor Regulatory Information The requirements cover a wide range of issues: environmental, ergonomic, usability, reduction of electric and magnetic fields, energy consumption and electrical safety. Why do we have environmentally labeled computers? In many countries, environmental labeling has become an established method for encouraging the adaptation of goods and services to the environment. The main problem, as far as computers and other electronics equipment are concerned, is that environmentally harmful substances are used both in the products and during their manufacture. Since it is not so far possible to satisfactorily recycle the majority of electronics equipment, most of these potentially damaging substances sooner or later enter nature. There are also other characteristic s of a computer, such as energy consumption levels, that are important from the viewpoints of both the work (internal) and natural ( external) environments. Since all methods of electricity generation have a negative effect on the environment (for example, acidic an d climate-influencing emissions, radioactive waste), it is vital to save energy. Electronics equipment in offices is often left running contin uously and thereby consumes a lot of energy. What does the environmental labeling involve? The environmental demands have been developed by Svenska Naturskyddsforeningen (The Swedish Society for 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 monitor, 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 computer shall be reasonable for the user. Below, you will find a brief summary of the environmental requirements met by this product.

Their purpose is to prevent, or at least to delay, the spread of fire. Up to 30% of the plastic in a computer casing can consist of flame retardant substances. Most flame retardants contain bromine or chlo ride, and those flame retardants are chemically related to another group of environmental toxins, PCBs. Both the flame retardants cont aining bromine or chloride and the PCBs are suspected of giving rise to severe health effects, including reproductive damage in fish-eating birds and mammals, due to the bio-accumulative*1 processes. Flame retardants have been found in human blood and researchers fear that disturbances in foetus development may occur. The relevant TCO '99 demand requires that plastic components weighing more than 25 grams must not contain flame retardants with organically bound bromine or ch lorine. Flame retardants are allowed in the printed circuit bo ards since no substitutes are available. Cadmium:*2* Cadmium is present in rechargeable batteries and in the colour- generating layers of certain computer displays. Cadmium damages the nervous system and is toxic in high doses. The relevant TCO '99 requirement states that batteries, the colour-generating layers of display screens and the electrical or electronics components must not contain any cadmium. l15_7_820. fm Page 52 Tues day, June 11, 2002 12:39 PM
English 53 hp L1520/hp L1720/hp L1820 LCD Monitor Regulatory Information Mercury:*2* Mercury is sometimes found in batteries, relays and switches. It damages the nervous system and is toxic in high doses. The relevant TCO '99 requirement states that batteries may not contain any mercury. It also demands that merc ury is not present in any of the electrical or electronics components associated with the labeled unit. There is however one exception. Mercury is, for the time being, permitted in the back light system of flat panel monitors as there today is no commercially availa ble alternative. TCO aims on removing this exception when a merc ury free alternative is available. CFCs (freons): The relevant TCO '99 requirement states that neither CFCs nor HCFCs may be used during the manufacture and assembly of the product. CFCs (freons) are some times used for washing printed circuit boards. CFCs break down ozone and thereby damage the ozone layer in the stratosphere, causing increased reception on earth of ultraviolet light with e.g. increased risks of skin cancer (malignant melanoma) as a consequence. Lead:*2* Lead can be found in picture tubes, display screens, solders and capacitors. Lead damages the nervous system and in higher doses, causes lead poisoning. The rele vant TCO '99 requirement permits the inclusion of lead since no replacement has yet been developed. 1* Bio-accumulative is defined as subs tances which accumulate within living organisms. *2* Lead, Cadmium and Mercury are heav y metals which are Bio-accumulative. l15_7_820. fm Page 53 Tues day, June 11, 2002 12:39 PM
