NEC PlasmaSync 4210W - Manual (Page 3)

To avoid damage and prolong operating life:
1. Use only with 120V 50/60Hz AC power supply. Con-
tinued operation at line voltages greater than 120 Volts
AC will shorten the life of the unit, and might even
cause a fire hazard.
2. Handle the unit carefully when installing it and do not
drop.
3. Locate set away from heat, excessive dust, and direct
sunlight.
4. Protect the inside of the unit from liquids and small
metal objects. In case of accident, unplug the unit and
have it serviced by an authorized NEC Service Center.
5. Do not hit or scratch the panel surface as this causes
flaws on the surface of the screen.
6. For correct installation and mounting it is strongly rec-
ommended to use a trained,authorized NEC dealer.
7. As is the case with any phosphor-based display (like a
CRT monitor, for example) light output will gradually
decrease over the life of a Plasma Display Panel.
Recommendations to avoid or minimize phosphor burn-in
Like all phosphor-based display devices and all other gas
plasma displays, PlasmaSync monitors can be susceptible
to phosphor burn under certain circumstances. Certain
operating conditions, such as the continuous display of a
static image over a prolonged period of time, can result in
phosphor burn if proper precautions are not taken. To pro-
tect your investment in this NEC PlasmaSync monitor,
please adhere to the following guidelines and recommen-
dations for minimizing the occurrence of image burn:
* Always enable and use your computer's screen saver
function during use with a computer input source.
* Display a moving image whenever possible.
* Always power down the monitor when you are finished
using it.
If the PlasmaSync monitor is in long term use or continu-
ous operation take the following measures to reduce the
likelihood of phosphor burn:
* Lower the Brightness and Contrast levels as much as
possible without impairing image readability.
* Display an image with many colors and color gradations
(ie. photographic or photo-realistic images).
* Create image content with minimal contrast between light
and dark areas, for example white characters on black
backgrounds. Use complementary or pastel color when-
ever possible.
* Avoid displaying images with few colors and distinct,
sharply defined borders between colors.
