NEC 4210W user manual To avoid damage and prolong operating life

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.
