Safety Precautions and Maintenance  
FOR OPTIMUM PERFORMANCE, PLEASE  
NOTE THE FOLLOWING WHEN SETTING UP  
AND USING THE MULTISYNC V SERIES  
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.  
Use the monitor in a clean, dry area.  
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 the 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.  
Keep the monitor away from high capacity transformers, electric  
monitors 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 earths 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.  
To separate the equipment from the power source you have to  
remove the plug from the inlet socket.  
When operating the MultiSync V Series with it is AC 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 approved by and comply with  
the safety standards of your country. (Type H05VV-F should be used  
except in UK)  
English-9  
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 you 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 liquit 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.  
Allow adequate ventilation around the monitor so that  
heat can properly dissipate. Do not block ventilated  
openings or place them monitor near a radiator or  
other heat sources. Do not put an thing 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  
Caution  
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:  
English-10  
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 30 cm and no further away than  
70 cm from your eyes. The optimal distance is 45 cm.  
Rest your eyes periodically by focusing on an object at least 6 m  
away. Blink often.  
Position the monitor at a 90° Xangle 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 monitorís 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 controls 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 (V521/V721) and 75-160 Hz (V921).  
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.

TCO99  
Congratulation! You have just purchased a TCO99  
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 potentiall y 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 TCO99 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.  
English-18  
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 impl ements i ts 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 retar ant  
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 re t a rdants have been found in human blood and  
researchers fear that disturbances in foetus development may occur.  
TCO99 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.  
TCO99 requirement permits the inclusion of lead since no replacement  
has yet been developed.  
English-19  
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.  
TCO99 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.  
TCO99 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 TCO99 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 accumul ate within living organisms.  
**Lead, Cadmium and Merc u ry are heavy metals which are Bio-accumulative.
