Safety Precautions and Maintenance
FOR OPTIMUM PERFORMANCE, PLEASE NOTE
THE FOLLOWING WHEN SETTING UP AND
USING THE ACCUSYNC LCD COLOUR MONITOR:
•
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 dangerous 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.
•
•
When operating the LCD monitor with its AC 125-240V power supply, use a power supply aord that matches the power
supply voltage of the AC power outlet being used. The power supply cord you use must have been approved by and
comply with the safety standards of your country. (Type H05VV-F should be used in Europe).
In U.K, 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.
•
•
Do not place any objects onto the monitor and do not use the monitor outdoors.
The inside of the fluorescent tube located within the LCD monitor contains mercury. Please follow the bylaws or rules of
your municipality to dispose of the tube properly.
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.
Do not bend power cord.
Do not use monitor in high temperature, humid, dusty, or oily areas.
Do not cover vent on monitor.
If monitor is broken, do not come in contact with the liquid crystal and handle with care.
•
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.
CAUTION
•
•
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.
•
Image Persistence: Image persistence is when a residual or “ghost” image of a previous image remains visible on the
screen. Unlike CRT monitors, LCD monitors’ image persistence is not permanent, but constant images being displayed for
a long period of time should be avoided.
To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an
image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to
erase the image.
NOTE: As with all personal display devices, NEC-Mitsubishi Electronics Display-Europe recommends using a moving
screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.
English-9
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.
•
•
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.

TCO’99
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
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.
environment and also to the further development
of environmentally adapted electronics products.
Cadmium**
Why do we have environmentally labelled computers?
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.
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.
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.
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.
*Bio-accumulative is defined as substances which accumulate
within living organisms.
**Lead, Cadmium and Mercury are heavy metals which are
Bio-accumulative.

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.
