Safety Precautions and Maintenance
FOR OPTIMUM PERFORMANCE, PLEASE NOTE
THE FOLLOWING WHEN SETTING UP AND USING
THE MULTISYNC 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.
•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.
•Do not bend power cord.
•Do not use monitor in high temperatured, humid, dusty, or oily areas.
•Do not cover vent on monitor.
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.
•If glass is broken, handle with care.
•If monitor or glass 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.
•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: Please be aware that LCD Technology may experience a phenomenon known as Image Persistence.
Image Persistence occurs 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 DISPLAY SOLUTIONS recommends displaying moving images and
using a moving screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.
CAUTION

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 50 cm.
•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.
•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.
Cleaning the LCD Panel
Recommended cleaning of the LCD:
•To remove dust and dirt from the surface of the LCD panel, wipe gently with a soft cloth.
•Do not rub the LCD panel with rough material.
•Do not press on the surface of the LCD panel.
To avoid scratches
•Do not touch LCD panel with hard objects.
•Use only a soft cloth for cleaning the surface of the LCD panel.
To avoid stains
•Clean fingerprints, water drips, chemical spills and etc. from the LCD panel immediately or discoloration and spot will
occur.
•If the LCD panel is rubbed with too much force, cracking may occur, which will lead to abnormalities in the display.
To avoid breakage or screen trouble
•Do not push hard on the LCD panel surface.
•Do not set heavy objects on the LCD panel surface.
•Do not leave the LCD panel under constant pressure.
Cleaning the Cabinet
•Unplug the power supply.
•Use a soft cloth.
•Dampen the cloth with a mild detergent mixed with water, wipe the cabinet and dry with a soft cloth.
NOTE:Many plastics are used on the cabinet surface. DO NOT clean with benzene, alkaline detergent, alcoholic system
detergent, glass cleaner, wax, polish cleaner, soap powder or insecticide. Do not touch the cabinet with rubber or
vinyl for a prolonged period. These types of fluids and fabrics can cause the paint to deteriorate, crack or peel.
