Technical InformationA12Low Radiation Compliance(MPR II)Self Diagnostics MessagesDDC (Display Data Channel)Low Radiation Compliance (MPR II), Self DiagnosticsMessages and DDC (Display Data Channel)This monitor meets one of the strictest guidelines available today for lowradiation emissions, offering the user extra shielding and an antistaticscreen coating. These guidelines, set forth by a government agency inSweden, limit the amount of emission allowed in the Extremely LowFrequency (ELF) and Very Low Frequency (VLF) electromagnetic range.Special Self Diagnostics messages will appear on the screen whenidentifying the following monitor conditions:CHECK SIGNAL CABLE This OSD may pop up when it is ON but nosignal is detected. In this case the messageCHECK SIGNAL CABLE will be highlighted,alerting you to check the signal cableconnections.OUT OF FREQUENCY This OSD may appear to inform you that thesignal being sent to the monitor is not withinits frequency range. In this case, you wouldneed to check the resolution and refresh rateyou have your video card set to, and adjust tobe within the range of the monitor.DDC is a communication channel over which the monitor automaticallyinforms the host system (PC) about its capabilities. This monitor has twoDDC function; DDC1 and DDC2B. DDC1 and DDC2B carry out uni-directional communication between the PC and the monitor. Under thesesituations, the PC sends display data to the monitor but not commands tocontrol the monitor settings. NOTEPC 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.SELF DIAGNOSTICSCHECK SIGNAL CABLENO SIGNALOUT OF FREQUENCY
Technical InformationA13Display Modes(Resolution)User ModesRecalling Display ModesVideo Memory ModesThe monitor has 26 memory locations for display modes, 16 of whichare factory preset to popular video modes.Modes 17-26 are empty and can accept new video data. If the monitordetects a new video mode that has not been present before or is not one ofthe preset modes, it stores the new mode automatically in one of the emptymodes starting with mode 17.If you use up the 10 blank modes and still have more new video modes, themonitor replaces the information in the user modes starting with mode 17.When your monitor detects a mode it has seen before, it automaticallyrecalls the image settings you may have made the last time you used thatmode.You may, however, manually force a recall of each of the 16 preset modesby pressing the Recall button. All preset modes are automatically recalled asthe monitor senses the incoming signal.The ability to recall the preset modes is dependent on the signal comingfrom your PC’s video card or system. If this signal does not match any of thefactory modes, the monitor automatically sets itself to display the image.12345678910111213141516640 x 350720 x 400640 x 480640 x 480640 x 480640 x 480800 x 600800 x 600800 x 600800 x 600800 x 600832 x 6241024 x 7681024 x 7681024 x 7681024 x 76831.4731.4731.4735.0037.5043.2735.1637.8848.0846.8853.6749.7348.3656.4860.0268.6770706067758556607275857560707585Display Modes (Resolution) Horizontal Freq.(kHz) Vertical Freq.(Hz)VGAVGAVGAMACVESAVESAVESAVESAMACVESAVESAMACVESAVESAVESAVESANote : This LCD monitor has been pre-adjusted to the video mode of VESA 1024x768 @60Hz.

A19AppendixCongratulations! Why do we haveenvironmentally labelledcomputers? Environmental Labelling of Personal ComputersYou have just purchased a TCO’99 approved and labelled product! Yourchoice has provided you with a product developed for professional use.Your purchase has also contributed to reducing the burden on theenvironment and also to the further development of environmentallyadapted electronics products.This product meets the requirements for the TCO’99 scheme whichprovides for an international environmental and quality labelling of personalcomputers. The labelling scheme was developed as a joint effort by theTCO (The Swedish Confederation of Professional Employees), SvenskaNaturskyddsforeningen (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, energyconsumption and electrical safety.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 methods ofelectricity generation have a negative effect on the environment (e.g.acidic and climate-influencing emissions, radioactive waste), it is vital tosave energy. Electronics equipment in offices is often left runningcontinuously and thereby consumes a lot of energy.
A20AppendixWhat does labellinginvolve?EnvironmentalrequirementsEnvironmental Labelling of Personal ComputersThe environmental demands impose restrictions on the presence and useof heavy metals, brominated and chlorinated flame retardants, CFCs(freons) and chlorinated solvents, among other things. The product mustbe prepared for recycling and the manufacturer is obliged to have anenvironmental policy which must be adhered to in each country where thecompany 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 time toreactivate 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 andvisual ergonomics and good usability.Below you will find a brief summary of the environmental requirementsmet by this product. The complete environmental criteria document maybe ordered from:TCO DevelopmentSE-114 94 Stockholm, SwedenFax: +46 8 782 92 07Email (Internet): development@tco.seCurrent information regarding TCO’99 approved andlabelled products may also be obtained via the Internet,using the address: http://www.tco-info.com/Flame retardantsFlame retardants are present in printed circuit boards, cables, wires,casings and housings. Their purpose is to prevent, or at least to delay thespread of fire. Up to 30% of the plastic in a computer casing can consistof flame retardant substances. Most flame retardants contain bromine orchloride, and those flame retardants are chemically related to anothergroup of environmental toxins, PCBs. Both the flame retardants containingbromine or chloride and the PCBs are suspected of giving rise to severehealth effects, including reproductive damage in fish-eating birds andmammals, due to the bio-accumulative* processes. Flame retardantshave been found in human blood and researchers fear that disturbances infoetus development may occur.
A21AppendixEnvironmental Labelling of Personal ComputersThe relevant TCO’99 demand requires that plastic components weighingmore than 25 grams must not contain flame retardants with organicallybound bromine or chlorine. Flame retardants are allowed in the printedcircuit boards since no substitutes are available.Cadmium**Cadmium is present in rechargeable batteries and in the colour-generatinglayers of certain computer displays. Cadmium damages the nervoussystem and is toxic in high doses. The relevant TCO’99 requirementstates that batteries, the colour-generating layers of display screens andthe electrical or electronics components must not contain any cadmium.Mercury**Mercury is sometimes found in batteries, relays and switches. It damagesthe nervous system and is toxic in high doses. The relevant TCO’99requirement states that batteries may not contain any mercury. It alsodemands that mercury is not present in any of the electrical or electronicscomponents associated with the labelled unit. There is however oneexception. Mercury is, for the time being, permitted in the back lightsystem of flat panel monitors as there today is no commercially availablealternative. TCO aims on removing this exception when a mercury freealternative is available.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. CFCsbreak down ozone and thereby damage the ozone layer in thestratosphere, causing increased reception on earth of ultraviolet light withe.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.* Bio-accumulative is defined as substances which accumulate within living organisms** Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.
