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�

CAUTION:

These servicing instructions are for use by qualied service personnel only.

To reduce the risk of electric shock, do not perform any servicing other than

that contained in the operating instructions unless you are qualied to do so.

Ventilation

The slots and openings in the TV are provided for necessary ventilation� To

ensure reliable operation of the TV and to protect it from overheating, these

slots and openings must never be blocked or covered�

Unless proper ventilation is provided, the TV may gather dust and get dirty�

For proper ventilation, observe the following:

• Do not install the TV face up, down or sideways�

• Do not install the TV turned over or upside down�

• Never cover the slots and openings with a cloth or other materials�

• Never block the slots and openings by placing the TV on a bed, sofa,

rug or other similar surface�

• Never place the TV in a conned space, such as a bookcase or built-in

cabinet, unless proper ventilation is provided�

Leave some space around the TV set as shown below� Otherwise, air-

circulation may be inadequate and will cause overheating, which may cause

a re or damage to the TV set.
