Safety Precautions and MaintenanceFOR OPTIMUM PERFORMANCE, PLEASE NOTETHE 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 cover\
s may expose
you to dangerous shock hazards or other risks. Refer all servicing to qu\
alified 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 to\
uch 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.
• The power supply cord you use must have been approved by and comply with\
 the safety standards of your country. (Type H05VV-F 3G 0.75mm
2 should be used in Europe).
• In U.K, use a BS-approved power cord with molded plug having a black (5\
A) fuse installed for use with this monitor.
• Do not place any objects onto the monitor and do not use the monitor out\
doors.
•
The lamps in this product contain mercury. Please dispose according to state, local or federal law.
• Do not bend, crimp or otherwise damage the power cord.
• Do not use monitor in high temperatured, humid, dusty, or oily areas.
• Do not cover vent on monitor.
• Do not touch LCD panel surface while transporting, mounting and setting.\
 Applying pressure on the LCD panel can cause serious damage.
• To prevent damage to the LCD monitor caused by tipping over due to earthq\
uakes or other shocks, make sure to install the monitor in a stable location and take measures to prevent falling.
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 instruct\
ions.
• If glass is broken, handle with care.
• If monitor or glass is broken, do not come in contact with the liquid cr\
ystal and handle with care.
• If you notice any structural damage such as cracks or unnatural wobbling\
.
•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 s\
ources. Do not put anything on
top of monitor.
• The power cable connector is the primary means of detaching the system f\
rom 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.
• Do not carry holding only the stand.
• 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 pre\
vious 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
 
						

							
English-4
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 slightl\
y below eye level. Your eyes should look slightly downward when viewing the middle of the sc\
reen.
• 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 6 m away. Blink often.
• Position the monitor at a 90° angle to windows and other light source\
s to minimize glare and reflections. Adjust the monitor tilt so that ceiling lights do not reflect on your sc\
reen.
• If reflected light makes it hard for you to see your screen, use an anti\
glare 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 re\
ference 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 t\
o 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
• When the liquid crystal panel becomes dusty or dirty, wipe gently with a soft cloth.
• Do not rub the LCD panel with coarse or hard material.
• Do not apply pressure to the LCD surface.
• Do not use OA cleaner as it will cause deterioration or discoloration to\
 the LCD surface.
Cleaning the Cabinet
• Unplug the power supply.
• Dampen a soft cloth with water and a neutral detergent. Gently wipe the \
cabinet then dry gently with a soft cloth.
NOTE: Many plastics are used on the surface of the cabinet. DO NOT clean with benzene, thinner, alkaline detergent,
alcoholic system detergent, glass cleaner, wax, polish cleaner, soap powder or insecticide. Do not touch rubber or
vinyl to the cabinet for a long period of time. These types of fluids and fabrics can cause the paint to deteriorate,
crack or peel.
