Safety Precautions and Maintenance
FOR OPTIMUM PERFORMANCE, PLEASE NOTE 
THE FOLLOWING WHEN SETTING UP AND USING  
THE MULTISYNC® LCD COLOR 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 ser vicing 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 MultiSync LCD monitor with its AC 125-240V 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 in Europe)
•  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.
•  Do not place any objects onto the monitor and do not use the monitor outdoors.
•  The inside of the flourescent 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 ser vicing to qualified service person
-nel 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 im-ages 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.
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.
Recommended Use
CAUTION
 
						

							
13
Recommended Use -continued
•  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 16 inches and no further 
away than 28 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.
•  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:
• Use the preset Size and Position controls with standard signals
• Use the preset Color Setting
• Use non-interlaced signals with a vertical refresh rate between 60-75Hz
• Do not use primary color blue on a dark background, as it is difficult to see and 
may produce eye fatigue to insufficient contrast.

Troubleshooting
No picture
• The signal cable should be completely connected to the display card/computer.
•  The display card should be completely seated in its slot.
•  Make sure the Vacation Switch is in the ON position.
•  Front Power Switch and computer power switch should be in the ON position.
• Check to make sure that a supported mode has been selected on the display card or sys-
tem being used. (Please consult display card or system manual to change graphics mode.)
•  Check the monitor and your display card with respect to compatibility and recom-
mended settings.
•  Check the signal cable connector for bent or pushed-in pins.
•  Check the signal input, “INPUT 1” or “INPUT 2”.
Power Button does not respond • Unplug the power cord of the monitor from the AC outlet to tur n off and reset the
  monitor.
•  Check the Vacation Switch on the back side of the monitor.
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.
As with all personal display devices, NEC DISPLAY SOLUTIONS recommends display
-
ing moving images and using a moving screen saver at regular inter vals whenever 
the screen is idle or turning off the monitor when not in use.
 
Image is unstable, unfocused or swimming is apparent •  Make sure Signal cable is properly attached.
•  Use the OSM Image Adjust controls to focus and adjust display by 
 
increasing or decreasing the fine total. When the display mode is changed, the OSM 
Image Adjust settings may need to be re-adjusted.
•  Check the monitor and your display card with respect to compatibility 
 
and recommended signal timings.
• If your text is garbled, change the video mode to non-interlace and use 60Hz refresh rate.
LED on monitor is not lit (no green or amber color can be seen)
•  Power Switch should be in the ON position and power cord should be connected.
•  Make sure the Vacation Switch is in the ON position.
Display image is not sized properly 
•  Use the OSM Image Adjust controls to increase or decrease the H.SIZE.
• Check to make sure that a supported mode has been selected on the display card or system 
being used. (Please consult display card or system manual to change graphics mode.)
No Video•  If no video is present on the screen, turn the Vacation Switch off and on again.
• Make certain the computer is not in a power-saving mode (touch the keyboard or mouse).
