Safety Precautions and Maintenance
FOR OPTIMUM PERFORMANCE, PLEASE NOTE THE
FOLLOWING WHEN SETTING UP AND USING
THE NEC DISPLAY:
•
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 display 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 an unbalanced or unstable cart, stand or table because the monitor
may fall, causing serious damage.
•
•
•
•
Do not place any objects onto the display and do not use the display outdoors.
The inside of the fluorescent tube located within the display 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 display.
•
•
•
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.
CAUTION
Image Persistence
Image persistence is when a residual or “ghost” image of a previous image remains visible on the
screen. Unlike CRT monitors, LCD displays’ 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 display for as long as the previous image was displayed.
For example, if an image was on the display for one hour and a residual image remains, the display
should be turned off for one hour to erase the image.
NOTE: As with all personal display devices, NEC-Mitsubishi Electronics Display recommends using a
moving screen saver at regular intervals whenever the screen is idle or turning off the display when
not in use.

CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR
CAN REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK THE
FOLLOWING WHEN YOU POSITION THE DISPLAY:
• For optimum results during self and copy calibrations,
allow 30 minutes for warm-up.
• Adjust the display 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 display 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 display 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.
• Clean the display surface with a lint-free, non-abrasive cloth. Case of persistent dirt,
wipe with cloth permeated by water, ethanol, isopropyl-alcohol completely. Avoid
using any cleaning solution or glass cleaner (ex Acid, Alkali and Acetone).
• Adjust the display’s brightness control to enhance readability.
• 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).
Ergonomics
To obtain the best possible ergonomics benefits, we recommend the following:
• Use the preset Size and Position controls with standard signals
• Use the DEFULT White Point Selection
