Image Persistence - NEC E424 User Manual

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 qualified 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 qualified 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 confined 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 fire or damage to the TV set.
