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 0.75 mm

2

 should be used in Europe).

• 

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 

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.

• 

Do not touch LCD panel surface while transporting, mounting and setting. 
Applying pressure on the LCD panel can cause serious damage.

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.
