Safety Precautions and Maintenance

FOR OPTIMUM PERFORMANCE, PLEASE NOTE

THE FOLLOWING WHEN SETTING UP AND

USING THE 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 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.

• The power supply cord you use must have been approved by and comply with the safety standards of your country.

(Type H05VV-F 3G 1mm

• In UK, use a BS-approved power cord with molded plug having a black (13A) fuse installed for use with this monitor.

• Do not place any objects onto the monitor and do not use the monitor outdoors.

•

The lamps in this product contain mercury. Please dispose according to state, local or federal law.

• Do not bend power cord.

• Do not use monitor in very hot, humid, dusty, or oily areas.

• Do not cover vent on monitor.

•Vibration can damage the backlight. Do not install where the monitor will be exposed to continual vibration.

• If monitor or glass is broken, do not come in contact with the liquid crystal and handle with care.

•To prevent damage to the LCD monitor caused by tipping over due to earthquakes 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 instructions.

• Allow adequate ventilation around the monitor so that heat can properly dissipate.

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 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 using a moving screen saver at regular
intervals whenever the screen is idle or turning off the monitor when not in use.

• The power cable connector is the primary means of detaching the system

• Handle with care when transporting. Save packaging for transporting.

• The monitor must be installed or carried by two or more people.

• Carry the monitor holding the built-in handle and bottom frames of the

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.

• 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:

• Adjust the Brightness until the background raster disappears.

• Do not position the Contrast control to its maximum setting.

• Use the preset Size and Position controls with standard signals.

• Use the preset Color Setting.

• Use non-interlaced signals with a vertical refresh rate of more than 60 Hz.

• Do not use primary color blue on a dark background, as it is difficult to see and may produce eye fatigue due to insufficient

contrast.

Cleaning the LCD Panel

• When the liquid crystal panel is stained with dust or dirt, please wipe gently with soft cloth.

• Please do not rub the LCD panel with hard or coarse material.

• Please do not apply pressure to the LCD surface.

• Please do not use OA cleaner as it will cause deterioration or discolor on the LCD surface.

Cleaning the Cabinet

• Unplug the power supply

• Gently wipe the cabinet with a soft cloth

•To clean the cabinet, dampen the cloth with a neutral detergent and water, wipe the cabinet and follow with a dry 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 time. These types of fluids and fabrics can cause the paint to deteriorate, crack or
peel.

The monitor must be installed or carried by two or more people.

1. Turn off the power to your computer.

2. For the PC or MAC with DVI digital output: Connect the DVI signal cable to the connector of the display card in your

system (Figure A.1). Tighten all screws.

For the PC with Analog output: Connect the 15-pin mini D-SUB to DVI-A signal cable (not included) to the connector of
the display card in your system (Figure A.2).

For the MAC: Connect the Macintosh cable adapter to the computer, then attach the 15-pin mini D-SUB signal cable to
the Macintosh cable adapter (Figure B.1).
