Important Information
Warnings and Safety Precaution
The NEC plasma monitor is designed and
manufactured to provide long, trouble-free service.
No maintenance other than cleaning is required. Use
a soft dry cloth to clean the panel. Never use
solvents such as alcohol or thinner to clean the panel
surface.
The plasma display panel consists of fine picture
elements (cells). Although NEC produces the plasma
display panels with more than 99.99 percent active
cells, there may be some cells that do not produce
light or remain lit.
For operating safety and to avoid damage to the unit,
read carefully and observe the following instructions.
To avoid shock and fire hazards:
1. Provide adequate space for ventilation to avoid internal
heat build-up. Do not cover rear vents or install the unit
in a closed cabinet or shelves.
The unit is equipped with cooling fans. If you install
the unit in an enclosure, make sure there is adequate
space at the top of the unit to allow hot air to rise and
escape. If the monitor becomes too hot, the overheat
protector will be activated and the monitor will be turned
off. If this happens, turn off the power to the monitor and
unplug the power cord. If the room where the monitor is
installed is particularly hot, move the monitor to a cooler
location, and wait for the monitor to cool for 60 minutes.
If the problem persists, contact your NEC dealer for
service.
2. Do not use the power cord polarized plug with extension
cords or outlets unless the prongs can be completely
inserted.
3. Do not expose the unit to water or moisture.
4. Avoid damage to the power cord, and do not attempt to
modify the power cord.
5. Unplug the unit during electrical storms or if the unit
will not be used over a long period.
6. Do not open the cabinet which has potentially dangerous
high voltage components inside. If the unit is damaged in
this way the warranty will be void. Moreover, there is a
serious risk of electric shock.
7. Do not attempt to service or repair the unit. NEC is not
liable for any bodily harm or damage caused if unqualified
persons attempt service or open the back cover. Refer
all service to authorized NEC Service Centers.
