Frequently Asked Questions - CM827ET HITACHI

How to connect the monitor to the computer?

Use the supplied video cable (ref. DC190018510). Connect one end to the monitor's input signal connector by tightening the screws, then the other end to the computer's graphics card. Then plug in the power cord and turn on the monitor first, then the computer.

What to do if the power indicator lights up orange?

This means the monitor is in power saving mode. Check that the signal cable is properly connected, that the computer is on, and press the Input Select button to ensure the correct input is selected.

How to adjust brightness and contrast?

Press the adjustment buttons when the OSD (on-screen menu) is not displayed. EasyMenu then shows brightness and contrast settings. Use the + and - buttons to adjust. The settings are automatically saved when the OSD disappears.

How to degauss the screen?

Go to the main menu, select 'DEGAUSSING' and press the + button (YES). This manually degausses the screen. The operation takes about 7 seconds and generates a magnetic field; keep magnetic media away.

How to clean the screen and cabinet?

Turn off the monitor and unplug it. For the cabinet, use a soft cloth slightly dampened with water or a mild synthetic detergent. For the screen, use a soft cloth (gauze) slightly dampened with water only. Never use solvents or abrasive cleaners.

What does the message 'INVALID SCAN FREQ' mean?

This message appears if the video signal from the computer is outside the supported frequency range (horizontal 31-107 kHz, vertical 50-160 Hz). Check your graphics card specifications and set a compatible resolution.

How to use the power saving function?

The monitor is VESA DPMS and ENERGY STAR compliant. It automatically enters standby (consumption < 10 W) or off (< 3 W) when the computer sends the appropriate signals. The indicator turns green in active mode and orange in standby.

How to adjust moiré?

Go to the 'DISPLAY' menu and select 'Moiré H.' or 'Moiré V.'. Use the - or + buttons to reduce the effect. Before adjusting, check the image size and brightness settings.

Can I connect two computers to the monitor?

Yes, the monitor has two input ports (INPUT1 and INPUT2). Connect each computer with a signal cable. Use the Input Select button on the front panel to switch between signals. Note that Plug & Play (DDC) is only available on INPUT1.

What to do if the image is distorted (trapezoid, pincushion, etc.)?

Use the OSD main menu to access geometric adjustments: TRAPEZOID, PINCUSHION, PARALLELOGRAM, PARALLEL EDGES, ROTATION. Adjust each parameter with the - or + buttons until a rectangular image is obtained.

TCO'99 STATEMENT

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.

What does the environmenal labelling involve?

The environmental demands has 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 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.

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.

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.
