IMPORTANT INFORMATION
________________________________
Still picture
If a still picture is displayed very long (several hours) on the picture screen, it
may happen that it remains visible some time as “ghost picture” when changing
the programme.
This phenomenon is caused by a kind of memory effect. To prevent this effect, it
is recommended to switch on a screen saver when the Planatron is operated in
connection with a PC.
Colour distortions
If the TV set is not used for a long period of time (over one year), it may happen
that colour distortions occur.
This effect can be considered normal for a plasma picture screen. After some
time, the colour distortions will disappear.
Failure of colour pixels
A plasma picture screen consists of about 1.2 million colour pixels.
It must be expected that a small percentage of theses pixels (0,001%) within an
industrial standard tolerance may be defect.
This is not visible in an animated picture.
Air pressure
The plasma picture screen functions technologically with inert gas under the
influence of air pressure.
In heights 2000m above sea level, the picture may become instable and the pic-
ture quality affected. However, if the set is operated 2000m below sea level
again, this effect disappears and the set will operate correctly again.
Humidity
The Planatron is not appropriate for regions with very high humidity (e.g. the
tropics). The maximum humidity must not exceed 85%):
