SET-UP AND SAFETY
_________________________________________________________________
This highly digitalised device offers optimum picture and sound quality.
The essential requirements are a perfectly functioning antenna system and a
high-quality antenna cable.
For this reason, avoid cable loops near the device.
Plasma screens operate using florescent materials. This technology can suffer
sticking effects under certain operating conditions. These include:
– Prolonged display of a freeze-frame
– Constant display of the same background
– Use of a picture format (such as 4:3) which does not fill the screen.
Once these sticking effects occur, they cannot normally be reversed.
To avoid sticking effects please note:
– During the first 100 operating hours, ensure that the television displays mostly
moving pictures or frequently changing stills which fill the screen
– Use a picture format which fills the screen (16:9)
– Always activate the screensaver when using a PC
– Decrease the contrast and brightness as much as possible
– Switch off the device when it is not in use
If a freeze-frame is on the plasma screen for a very long time (several hours), it
is possible that this will be visible as a ghosting effect for some time when you
switch to another channel. However, after a certain amount of time this ghosting
disappears again.
This is caused by a type of memory effect. In order to prevent this effect,
we recommend activating the screen saver when using a PC.
After a lengthy period without use (longer than one year) a temporary colour
discrepancy is possible in some circumstances.
This effect is normal for plasma screens. After a while these colour discrepancies
disappear again.
A plasma screen is made up of around 1.2 million colour pixels.
Within the industrial standard tolerance, a very small number of pixels (0.001%)
can be defective. This is not regarded as a device defect within the warranty.
The plasma screen functions with inert gases and air pressure.
At 2000 m above sea-level or higher, the picture can become unstable and the
picture quality is reduced. However, when the device is returned to below
2000 m above sea level, this effect disappears and the device functions perfectly.
Note:
Do not connect any other equipment while the device is switched on. Switch off
the other equipment as well before connecting it.
Only plug the device into the mains socket after you have connected the external
devices and the antenna.
