Safety Precautions and Maintenance

FOR OPTIMUM PERFORMANCE, PLEASE NOTE

THE FOLLOWING WHEN SETTING UP AND USING

THE MULTISYNC LCD COLOUR 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 0.75mm

• In U.K, use a BS-approved power cord with molded plug having a black (5A) fuse installed for use with this monitor.

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

• Use supplied AC Adapter. Do not place any objects onto the AC Adapter and do not use the AC Adapter outdoors.

• 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 monitor and AC adapter.

• 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 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.

• When AC adapter 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 you notice any structural damage such as cracks or unnatural wobbling.

• 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

CAUTION

• 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.

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.

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.

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

• Do not carry holding only the stand.

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.

• 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 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 is stained with dust or dirt, please wipe with soft cloth gently.

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

• Please do not apply pressure to the LCD surface.

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

Cleaning the Cabinet

• Unplug the power supply cord from the wall outlet.

• 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.

2. Put the upper hooks of the stand in the slot of the monitor then push stand into monitor in direction
of the arrow as shown in Figure 1 and confirm that the stand is locked.

NOTE: Handle with care when pulling the stand.

3. Attach the base stand to stand and turn the connecting screw at the bottom of the base
stand fully so that it is completely fixed (Figure 2).

NOTE: Reverse this procedure if you need to re-pack the monitor.

To attach the MultiSync LCD monitor to your computer system, follow these instructions:

1. Turn off the power of your computer.

2. For 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 PC with Analog output: Connect the 15-pin mini D-SUB to DVI-A signal cable
to the connector of the display card in your system (Figure A.2). Tighten all screws.

For MAC: Connect the Macintosh cable adapter to the computer, then attach the
15-pin mini D-SUB to DVI-A signal cable to the Macintosh cable adapter (Figure A.3).
Tighten all screws.
