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

minimize 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

antiglare 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.

English-18

•

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 realize 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 to insufficient contrast.

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.

• Check the Vacation Switch should be in the ON Position. Front power

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

• 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.)

• 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.

• Check the signal input, “INPUT 1” or “INPUT 2”.

Power Button does not respond

• Unplug the power cord of the monitor from the AC outlet to turn off

and reset the monitor.

• Check the Vacation Switch on the right hand side of the monitor.

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.

English-24

Image is unstable, unfocused or swimming is

apparent

• Signal cable should be completely attached to the computer.

• Use the OSM Image Adjust controls to focus and adjust display by

increasing or decreasing the fine total. When the display mode is

changed, the OSM 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 OSM

warning “OUT OF RANGE” is displayed: Either signal clock or

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

• OSM warning “OUT OF RANGE” is displayed on a blank 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 OSM 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).

TCO’99

This is a translation of the original English TCO'99 document.

MultiSync LCD1850E (LCD1850E)

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).

English-26

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

bioaccumulative* 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.

English-27

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**
