necessary to:
•Be familiar with specialized test equipment, and
•Be careful to follow all safety procedures to minimize danger to themselves and their coworkers.
To avoid electrical shocks, this equipment should be used with an appropriate power cord.
This equipment utilized a micro-gap power switch. Turn off the set by first pushing power switch. Next,
remove the power cord from the AC outlet.
To prevent fire or shock hazards, do not expose this unit to rain or moisture.
This symbol warns the personnel that un-insulated voltage within the unit may have sufficient
magnitude to cause electric shock.
This symbol alerts the personnel that important literature concerning the operation and
maintenance of this unit has been included.
Therefore, it should be read carefully in order to avoid any problems.
PRODUCT SAFETY CAUTION
1. When parts replacement is required for servicing, always use the manufacturer's specified replacement.
2. When replacing the component, always be certain that all the components are put back in the place.
3. As for a connector, pick and extract housing with fingers properly since a disconnection and improper
contacts may occur, when wires of the connector are led.
4. Use a proper screwdriver. If you use screwdriver that does not fit, you may damage the screws.

Recommended Use
• 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 flourescent tube located within the LCD monitor contains
mercury. Please follow the bylaws or rules of your municipality to dispose of the
tube properly.
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.
•Do not bend power cord.
•Do not use monitor in high temperatured, humid, dusty, or oily areas.
Safety Precautions and Maintenance
FOR OPTIMUM PERFORMANCE, PLEASE NOTE THE
FOLLOWING WHEN SETTING UP AND USING
THE LCD COLOR MONITOR:
•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

3–User’s Manual
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 40 cm and no further away
than 70 cm from your eyes. The optimal distance is 58 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 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 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 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 Color Setting
•Use non-interlaced signals with a vertical refresh rate between 60 - 75 Hz
•Do not use primary color blue on a dark background, as it is difficult to see and
may produce eye fatigue to insufficient contrast
•Image Persistence: Image persistence is 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-Mitsubishi Electronics Display-
Europe recommends using a moving screen saver at regular intervals whenever
the screen is idle or turning off the monitor when not in use.
CORRECT PLACEMENTAND ADJUSTMENT OF THE MONITOR
CAN REDUCE EYE, SHOULDERAND NECK FATIGUE. CHECK
THE FOLLOWING WHEN YOU POSITION THE MONITOR.
