Congratulations! You have just purchased a TCO’99 approved and labeled 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.

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 the manufacturing. Since it has not been possible for the majority of electronics equipment to be recycled in a satisfactory way, 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 conventional electricity generation have a negative effect on the environment (acidic and climate-influencing emissions, radioactive waste, etc.), it is vital to conserve energy. Electronics equipment in offices consume an enormous amount of energy since they are often left running continuously.

What does labelling involve?

This product meets the requirements for the TCO’99 scheme which provides for international and environmental 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) and Statens Energimyndighet (The Swedish National Energy Administration). The requirements cover a wide range of issues: environment, ergonomics, usability, emission of electrical and magnetic fields, energy consumption and electrical and fire safety. The environmental demands concern 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 plan 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.

Environmental Requirements

Flame retardants

Flame retardants are present in printed circuit boards, cables, wires, casings and housings. In turn, they delay the spread of fire. Up to thirty percent of the plastic in a computer casing can consist of flame retardant substances. Most flame retardants contain bromine or chloride and these are related to another group of environmental toxins, PCBs, which are suspected to give rise to severe health effects, including reproductive damage in fisheating 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. TCO’99 demand requires that plastic components weighing more than 25 grams must not contain flame retardants with organically bound chlorine and bromine. Flame retardants are allowed in the printed circuit boards since no substitutes are available.

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. TCO’99 requirement permits the inclusion of lead since no replacement has yet been developed.

Cadmium**

Cadmium is present in rechargeable batteries and in the colourgenerating layers of certain computer displays. Cadmium damages the nervous system and is toxic in high doses. TCO’99 requirement states that batteries, the colourgenerating 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, Mercury damages the nervous system and is toxic in high doses. TCO’99 requirement states that batteries may not contain any Mercury. It also demands that no mercury is present in any of the electrical or electronics components associated with the display unit.

CFCs (freons)

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 consequent increased risks of skin cancer (malignant melanoma). The relevant TCO’99 requirement; Neither CFCs nor HCFCs may be used during the manufacturing and assembly of the product or its packaging.

*Bio-accumulative is defined as substances which accumulate within living organisms. **Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative. To obtain complete information on the environmental criteria document, order from:

CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR

CAN REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK

THE FOLLOWING WHEN YOU POSITION THE MONITOR:

• For optimum performance, allow 20 minutes for warm-up.

• Adjust the monitor height so that the top of the screen is at or slightly below eye level. Your eyes should look slightly downward when viewing the middle of the screen.

• Position your monitor no closer than 40 cm and no further away than 70 cm from your eyes. The optimal distance is 58 cm.

• Rest your eyes periodically by focusing on an object at least 6 m away. Blink often.

• Position the monitor at a 90° angle to windows and other light sources to minimise glare and reflections. Adjust the monitor tilt so that ceiling lights do not reflect on your screen.

• If reflected light makes it hard for you to see your screen, use an anti-glare filter.

• Clean the LCD monitor surface with a lint-free, non-abrasive cloth. Avoid using any cleaning solution or glass cleaner!

• Adjust the monitor’s brightness and contrast controls to enhance readability.

• Use a document holder placed close to the screen.

• Position whatever you are looking at most of the time (the screen or reference material) directly in front of you to minimize turning your head while you are typing.

CAUTION

1-13

English-8

• Avoid displaying fixed patterns on the monitor for long periods of time to avoid image persistence (after-image effects).

• Get regular eye checkups.

Ergonomics

To realise the maximum ergonomics benefits, we recommend the following:

• Use the preset Size and Position controls with standard signals.

• Use the preset Colour Setting.

• Use non-interlaced signals with a vertical refresh rate between 60-75 Hz.

• Do not use primary colour blue on a dark background, as it is difficult to see and may produce eye fatigue due to insufficient contrast.

Features

Reduced Footprint: Provides the ideal solution for environments requiring superior image quality but with size and weight

limitations. The monitor’s small footprint and low weight allow it to be moved or transported easily from one location to another.

Colour Control System: Allows you to adjust the colours on your screen and customize the colour accuracy of your monitor to a variety of standards.

OSD (On-Screen Manager) Controls: Allow you to quickly and easily adjust all elements of your screen image via simple to use on-screen menus.

ErgoDesign Features: Enhance human ergonomics to improve the working environment, protect the health of the user and save money. Examples include OSD controls for quick and easy image adjustments, tilt base for preferred angle of vision, small footprint and compliance with MPRII and TCO guidelines for lower emissions.

Plug and Play: The Microsoft solution with the Windows 95/98/2000 operating system facilitates setup and installation by allowing the monitor to send its capabilities (such as screen size and resolutions supported) directly to your computer, automatically optimizing display performance.

IPM (Intelligent Power Manager) System: Provides innovative power-saving methods that allow the monitor to shift to a lower power consumption level when on but not in use, saving two-thirds of your monitor energy costs, reducing emissions and lowering the air conditioning costs of the workplace.

Multiple Frequency Technology: Automatically adjusts monitor to the display card’s scanning frequency, thus displaying the resolution required.

FullScan Capability: Allows you to use the entire screen area in most resolutions, significantly expanding image size.

Wide Viewing Angle Technology: View angle is the angle at which the contrast ratio is greater than 10. The angles are

determined for the horizontal or x axis and the vertical or y axis with repect to the z axis which is nornal to the LCD surface. (Viewing angle: x axis 60

, y axis 45o)

VESA Standard Mounting Interface: Allows users to connect their MultiSync monitor to any VESA standard (75 mm pitch) third party mounting arm or bracket. Allows for the monitor to be mounted on a wall or an arm using any third party compliant device.

Troubleshooting

No picture

• The signal cable should be completely connected to the display card/computer.

• The display card should be completely seated in its slot.

• Front power Switch and computer power switch should be in the ON position.

• Make sure that a supported mode has been selected on the display card or system being used. (Please consult display

card or system manual to change graphics mode.)

• Check the monitor and your display card with respect to compatibility and recommended settings.

• Check the signal cable connector for bent or pushed-in pins.

Image persistence

• Image persistence is when a “ghost” of an image remains on the screen even after the monitor has been turned off.

Unlike CRT monitors, LCD monitors’ image persistence is not permanent. To alleviate image persistence, turn the monitor off for as long as an image was displayed. If an image was on the monitor for one hour and a “ghost” of that image remains, the monitor should be turned off for one hour to erase the image.

NOTE: As with all personal display devices, NEC-Mitsubishi Electronic Displays recommends using a screen saver at

regular intervals whenever the screen is idle.

Image is unstable, unfocused or swimming is apparent

• Signal cable should be completely attached to the computer.

• Use the OSD Image Adjust controls to focus and adjust display by increasing or decreasing the fine total. When the

display mode is changed, the OSD Image Adjust settings may need to be readjusted.

• Check the monitor and your display card with respect to compatibility and recommended signal timings.

• If your text is garbled, change the video mode to non-interlace and use 60 Hz refresh rate.

Message “OUT OF RANGE” is displayed (screen is either blank or shows rough images only)

• Image is displayed only roughly (pixels are missing) and OSD warning “OUT OF RANGE” is displayed: Either signal

clock or resolution is too high. Choose one of the supported modes.

• OSD warning “OUT OF RANGE” is displayed on a screen: Signal frequency is out of range. Choose one of the

supported modes.

LED on monitor is not lit (no green or amber colour can be seen)

• Power Switch should be in the ON position and power cord should be connected.

Display image is not sized properly

• Use the OSD Image Adjust controls to increase or decrease the Coarse total.

• Check to make sure that a supported mode has been selected on the display card or system being used. (Please

consult display card or system manual to change graphics mode.)

No Video

• If no video is present on the screen, turn the Power button off and on again.

• Make certain the computer is not in a power-saving mode (touch the keyboard or mouse).
