Introduction
Introduction
Introduction
What is a Plasma Display Panel?
If voltage is applied to gas within glass panels, ultraviolet rays are produced and fused with a fluorescent substance. At that
instant, light is emitted. A Plasma Display is a next generation flat Display using this phenomenon.
160° - Wide angle range of vision
Your flat panel plasma screen offers an exceptionally broad viewing angle -- over 160 degrees. This means that the display is
clear and visible to viewers anywhere in the room.
Wide Screen
The screen of the Plasma Display is 42 or 50" so wide that your viewing experience is as if you are in a theater.
Versatile
The light weight and thin size makes it easy to install your plasma display in a variety of locations where conventional TVs would
not fit.
The Plasma Monitor Manufacturing Process: Why minute colored dots may be present on the Plasma
Monitor screen
The Plasma Display Panel which is the display device of this product is composed of 0.9 to 2.2 million cells. A few cell defects will
normally occur in the Plasma Monitor manufacturing process. Several minute colored dots visible on the screen should be accept-
able. This also occurs in other Plasma Monitor manufacturers' products and the tiny dots appearing does not mean that this
Plasma Monitor is defective. Thus a few cell defects are not sufficient cause for the Plasma Monitor to be exchanged or returned.
Our production technology is designed to minimize cell defects during the manufacture and operation of this product.
Cooling Fan Noise
In the same way that a fan is used in a PC computer to keep the CPU (Central Processing Unit) cool, the Plasma Monitor is
equipped with cooling fans to cool the Monitor and improve its reliability. Therefore, a certain level of noise could occur while the
fans are operating and cooling the Plasma Monitor.
The fan noise doesn't have any negative effect on the Plasma Monitor's efficiency or reliability. The noise from these fans is nor-
mal during the operation of this product. We hope you understand that a certain level of noise from the cooling fans is acceptable
and is not sufficient cause for the Plasma Monitor to be exchanged or returned.
WARNING
TO REDUCE THE RISK OF FIRE AND ELECTRIC SHOCK, DO NOT EXPOSE THIS PRODUCT TO
RAIN OR MOISTURE.

Ensure that the following accessories are included with your plasma display. If an accessory is missing, please contact the dealer
where you purchased the product.
Video cables Audio cables
-Optional extras can be changed or modified for quality improvement without any notification new optional extras can be added.
- Contract your dealer for buying these items.
