Technical Information Energy Saving Design This monitor complies with the EPA's Energy Star program, which is a program designed to have manufacturers of computer equipment build circuitry into their products to reduce power consumption during time of non-use. This monitor also goes into its energy saving mode if you exceed the monitor's operating limits, such as the maximum resolution of 1024 x 768 or the frequency refresh rates of 31-69kHz horizontal or 56-85Hz vertical. When this monitor is used with a Green or EPA Energy Star PC, or a PC with a screen blanking software following the VESA Display Power Management Signalling (DPMS) protocol, this monitor can conserve significant energy by reducing power consumption during periods of nonuse. When the PC goes into the energy saving mode, the monitor will go into a suspended operation state, indicated by the Power LED light changing from a green color to an amber color. After an extended period in the suspended mode, the monitor will then enter a semi-OFF mode to conserve more energy. In the semi-OFF mode or DPMS OFF mode as we call it in our specifications, the Power LED will still show an amber color. When you awaken your PC by hitting a key or moving the mouse, the monitor will also awaken to its normal operating mode, indicated by the green Power LED light. By following these conventions, the power consumption can be reduced to the following levels: Power Consumption A11 Mode Hori. Sync Verti. Sync Video Normal(Max.) On On Normal ≤ 40W Green Stand-by Off On Off ≤ 3W Amber Suspend On Off Off ≤ 3W Amber Power Off Off Off Off ≤ 3W Amber Power Consumption LED Color Technical Information Low Radiation Compliance (MPR II), Self Diagnostics Messages and DDC (Display Data Channel) Low Radiation Compliance (MPR II) This monitor meets one of the strictest guidelines available today for low radiation emissions, offering the user extra shielding and an antistatic screen coating. These guidelines, set forth by a government agency in Sweden, limit the amount of emission allowed in the Extremely Low Frequency (ELF) and Very Low Frequency (VLF) electromagnetic range. Self Diagnostics Messages Special Self Diagnostics messages will appear on the screen when identifying the following monitor conditions: CHECK SIGNAL CABLE SELF DIAGNOSTICS CHECK SIGNAL CABLE NO SIGNAL This OSD may pop up when it is ON but no signal is detected. In this case the message CHECK SIGNAL CABLE will be highlighted, alerting you to check the signal cable connections. OUT OF FREQUENCY OUT OF FREQUENCY DDC (Display Data Channel) This OSD may appear to inform you that the signal being sent to the monitor is not within its frequency range. In this case, you would need to check the resolution and refresh rate you have your video card set to, and adjust to be within the range of the monitor. DDC is a communication channel over which the monitor automatically informs the host system (PC) about its capabilities. This monitor has two DDC function; DDC1 and DDC2B. DDC1 and DDC2B carry out unidirectional communication between the PC and the monitor. Under these situations, the PC sends display data to the monitor but not commands to control the monitor settings. NOTE PC must support DDC functions to do this. If your monitor is displaying a mono chrome image or the wrong resolution, select the DDC OFF function. A12 Technical Information Video Memory Modes The monitor has 26 memory locations for display modes, 16 of which are factory preset to popular video modes.

User Modes Modes 17-26 are empty and can accept new video data. If the monitor detects a new video mode that has not been present before or is not one of the preset modes, it stores the new mode automatically in one of the empty modes starting with mode 17. If you use up the 10 blank modes and still have more new video modes, the monitor replaces the information in the user modes starting with mode 17. Recalling Display Modes When your monitor detects a mode it has seen before, it automatically recalls the image settings you may have made the last time you used that mode. You may, however, manually force a recall of each of the 16 preset modes by pressing the Recall button. All preset modes are automatically recalled as the monitor senses the incoming signal. The ability to recall the preset modes is dependent on the signal coming from your PC’s video card or system. If this signal does not match any of the factory modes, the monitor automatically sets itself to display the image. A13 Technical Information Troubleshooting Check the following before calling for service. Display Position is incorrect. Push the SET Button. If the results are unsatisfactory, adjust the image position using the H position and V position icon in the on screen display. On the screen background, vertical bars or stripes are visible. Push the SET Button. If the results are unsatisfactory, decrease the vertical bars or stripes using the CLOCK icon in the on screen display. Any horizontal noise appearing in any image or characters are not clearly portraid. Push the SET Button.

Appendix Environmental Labelling of Personal Computers 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 the environment 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 of personal computers. The labelling scheme was developed as a joint effort by the TCO (The Swedish Confederation of Professional Employees), Svenska Naturskyddsforeningen (The Swedish Society for Nature Conservation), Statens Energimyndighet (The Swedish National Energy Administration) and SEMKO AB. The requirements cover a wide range of issues: 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 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 characteristics 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 (e.g. acidic and climate-influencing emissions, radioactive waste), it is vital to save energy. Electronics equipment in offices is often left running continuously and thereby consumes a lot of energy. A19 Appendix Environmental Labelling of Personal Computers What does labelling involve? The environmental 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 to reactivate the computer shall be reasonable for the user. Labelled products must meet strict environmental demands, for example, in respect of the reduction of electric and magnetic fields, physical and visual ergonomics and good usability. Below you will find a brief summary of the environmental requirements met by this product. The complete environmental criteria document may be ordered from: TCO Development SE-114 94 Stockholm, Sweden Fax: +46 8 782 92 07 Email (Internet): development@tco.se Current information regarding TCO’99 approved and labelled products may also be obtained via the Internet, using the address: http://www.tco-info.com/ Environmental requirements Flame retardants Flame retardants are present in printed circuit boards, cables, wires, casings and housings. 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 chloride, and those flame retardants are chemically related to another group of environmental toxins, PCBs. Both the flame retardants containing 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* processes. Flame retardants have been found in human blood and researchers fear that disturbances in foetus development may occur. A20 Appendix Environmental Labelling of Personal Computers The relevant TCO’99 demand requires that plastic components weighing more than 25 grams must not contain flame retardants with organically bound bromine or chlorine. Flame retardants are allowed in the printed circuit boards since no substitutes are available. Cadmium** 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. Mercury** 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 mercury is not present in any of the electrical or electronics components associated with the labelled 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 available alternative. TCO aims on removing this exception when a mercury 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 sometimes 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** 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 relevant TCO’99 requirement permits the inclusion of lead since no replacement has yet been developed. * Bio-accumulative is defined as substances which accumulate within living organisms ** Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.
