TCO’99
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
electron-ics 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 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).
Approval requirements cover a wide range of issues: environment,
ergonomics, usability, emission of electric and magnetic fields, energy
consumption and electrical and fire safety.
English-4
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:

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.
English-5
English
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 colourgenerating 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 no mercury is present in any of the electrical or
electronics components associated with the labelled unit.
CFCs (freons)
The relevant TCO‘99 requirement states that neither CFCs nor HCFCs
may be used during the manufacturing 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.

• DO NOT OPEN THE MONITOR. There are no user serviceable parts inside and
opening or removing covers may expose you to dangerous shock hazards or
other risks. Refer all servicing to qualified service personnel.
• Do not spill any liquids into the cabinet or use your monitor near water.
• Do not insert objects of any kind into the cabinet slots, as they may touch
danger-ous voltage points, which can be harmful or fatal or may cause electric
shock, fire or equipment failure.
• Do not place any heavy objects on the power cord. Damage to the cord may
cause shock or fire.
• Do not place this product on a sloping or unstable cart, stand or table, as the
monitor may fall, causing serious damage to the monitor.
• Keep the monitor away from high capacity transformers, electric motors and
other devices such as external speakers or fans, which may create strong
magnetic fields.
• If possible, position the monitor so that it is facing the east to minimize the
effects of the earth’s magnetic field.
• Changing the direction of the monitor while it is powered on may cause image
discoloration. To correct this, turn the monitor off for 20 minutes before powering
it back on.
• When operating the MultiSync FE750+ with its AC 100-120/220-240V worldwide
power supply, use a power supply cord that matches the power supply voltage
of the AC power outlet being used. The power supply cord you use must have
been ap-proved by and comply with the safety standards of your country. (Type
H05VV-F should be used except in UK)
• In UK, use a BS-approved power cord with molded plug having a black (5A) fuse
installed for use with this monitor. If a power cord is not supplied with this
monitor, please contact your supplier.
Immediately unplug your monitor from the wall outlet and refer servicing to qualified
service personnel under the following conditions:
• When the power supply cord or plug is damaged.
• If liquid has been spilled, or objects have fallen into the monitor.
• If the monitor has been exposed to rain or water.
• If the monitor has been dropped or the cabinet damaged.
• If the monitor does not operate normally by following operating instructions.
English-14
• Allow adequate ventilation around the monitor so that heat can
properly dissipate. Do not block ventilated openings or place the
monitor near a radiator or other heat sources. Do not put
anything on top of monitor.
• The power cable connector is the primary means of detaching
the system from the power supply. The monitor should be
installed close to a power outlet which is easily accessible.
• Handle with care when transporting. Save packaging for
transporting.
CORRECT PLACEMENT AND ADJUSTMENT OF THE
MONITOR CAN REDUCE EYE, SHOULDER AND NECK
FATIGUE. CHECK THE FOLLOWING WHEN YOU POSITION
THE MONITOR:
• 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 16 inches and no
further away than 24 inches from your eyes. The optimal
distance is 20 inches.
• Rest your eyes periodically by focusing on an object at
least 20 feet 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 anti-glare filter.
• Clean your monitor regularly. Use a lint-free, non-abrasive cloth and a non-
alcohol, neutral, non-abrasive cleaning solution or glass cleaner to minimize
dust.
• 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.
• Get regular eye checkups.
Ergonomics
To realize the maximum ergonomics benefits, we recommend the following:
• Adjust the Brightness until the background raster disappears
• Do not position the Contrast control to its maximum setting
• Use the preset Size and Position controls with standard signals
• Use the preset Color Setting and Sides Left/Right controls
• Use non-interlaced signals with a vertical refresh rate between 75-120Hz
• Do not use primary color blue on a dark background, as it is difficult to see and
may produce eye fatigue due to insufficient contrast

Troubleshooting
No picture
• Display card should be completely seated in its slot.
• Power Button and computer power switch should be in the ON
position.
• Signal cable should be completely connected to display card/
computer.
• Check connector for bent or pushed-in pins.
Image is scrolling or unstable
• Signal cable should be completely attached to the computer.
• Check pin assignments and signal timings of the monitor and your
display card with respect to recommended timings and pin
assignments.
• If the Macintosh cable adapter is used, check for proper connection
or make sure the display card is Macintosh compatible and that the
card is properly seated in the computer.
LED on monitor is not lit (no green or orange color can be seen)
• Power Switch should be in the ON position and power cord should be
connected.
Picture is fuzzy or color looks blotchy
• Adjust Brightness and Contrast Controls.
• Access the Degauss Control through OSM controls. Activate the
Degauss Control.
CAUTION: A minimum interval of 20 minutes should elapse before
the Deguass Control is used a second time when not
switching between modes.
Picture bounces or a wavy pattern is present in the picture
• Move electrical devices that may be causing electrical interference
away from the monitor.
Edges of the display image are not square
• Use the OSM Geometry Controls to straighten the edges.
• If possible, position the front of the monitor facing east.
Display image is not centered, too small, or too large
• Use the OSM Size and Position Controls to adjust the image.
English-19
English
Thin horizontal lines appear on your screen
• Thin horizontal lines are normal for an aperture grille CRT and are
not a malfunction. These are shadows from the damper wires used to
stabilize the aperture grille and are most noticeable when the
screen’s background is light (usually white).
Black vertical lines are visible on the screen
• Thin vertical black lines on one or both sides of the screen. This
minor condition is caused by grille element overlap which can occur
during shipping.
• Position an open white window over the affected area of the screen
and maximize the brightness and contrast controls. This will cause
localized heating of the overlap which will clear in a few minutes. Be
sure to readjust the brightness and contrast controls back to the
normal viewing level after this procedure.
