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 qualiﬁ ed 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, ﬁ re or equipment failure.

• Do not place any heavy objects on the power cord. Damage to the cord may cause shock or ﬁ re.

• 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 (5A) fuse installed for use with this monitor.

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

• Do not bend power cord.

• Do not use monitor in high temperatured, 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 turn off the power, unplug your monitor from the wall outlet and move to a safe location then refer servicing to qualiﬁ ed service personnel under the following conditions. If the monitor is used in this condition, the monitor may cause fall, ﬁ re and electric shock:

• If the monitor stand has been cracked or peeled.

• If the monitor has been wobbled.

• If the monitor has an unusual odor.

• 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. Do not block ventilated

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 from the power supply.

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

• Do not touch LCD panel surface while transporting, mounting and setting.

openings or place the monitor near a radiator or other heat sources. Do not put anything on top of monitor.

The monitor should be installed close to a power outlet which is easily accessible.

Applying pressure on the LCD panel can cause serious damage.

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 the display to 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 (15.75 inches) and no further away than

70 cm (27.56 inches) from your eyes. The optimal distance is 50 cm (19.69 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 reﬂ ections. Adjust the monitor tilt so that ceiling lights do not reﬂ ect on your screen.

• If reﬂ ected light makes it hard for you to see your screen, use an anti-glare ﬁ lter.

• 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 ﬁ xed 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 beneﬁ ts, we recommend the following:

• To avoid eye fatigue, adjust the brightness to a moderate setting. Place a sheet of white paper next to the LCD screen for

luminance reference.

• 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 60 Hz.

• Do not use primary color blue on a dark background, as it is difﬁ cult to see and may produce eye fatigue due to insufﬁ cient

contrast.

Cleaning the LCD Panel

• When the LCD is dusty, please gently wipe with a 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 discoloration 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 ﬂ uids and fabrics can cause the paint to deteriorate, crack or peel.

4. Connect all cables to the appropriate connectors (Figure C.1). When using the USB cable, connect the B type connector

to the USB upstream port on the right back side of the monitor and the A type connector to the downstream port on the

computer (Figure C.1a). If using the cord from a USB device, plug into the downstream port of the monitor.

NOTE: Incorrect cable connections may cause abnormal operation, damage display quality/components of LCD module and/

or shorten the module’s life.

NOTE: Use an audio cable without a built-in resistor. Using an audio cable with a built-in resistor turns down the sound.
