Warning concerning stationary images on the TV screen (only for PDP Displays)
A characteristic of Plasma Display Panels is that displaying the same image for a long time can cause a permanent after-image to
remain on the screen.This is called phosphor burn in.
Normal use of the TV should involve the showing of pictures that contain constantly moving and changing images that fill the
screen.
Examples of stationary images (this is not an all-inclusive list, you may encounter others in your viewing):
•
TV and DVD menus : listings of DVD disk content;
• Black bars : when black bars appear at the left and right side of the screen, it is recommended to change to a picture format
so that the picture fills the entire screen;
• PIP and Multipip : do not view for long periods of time using the PIP function or Multipip function;
• TV channel logo : present a problem if they are bright and stationary. Moving or low-contrast graphics are less likely to cause
uneven aging of the screen;
• Stock market stickers : presented at the bottom of the TV screen;
• Shopping channel logos and pricing displays : bright and shown constantly or repeatedly in the same location on the TV
screen.
Examples of still pictures also include logos, computer images, time display, teletext and images displayed in 4:3 mode, static
images or characters, etc.
Notes:
- reduce contrast and brightness when viewing
- once burn-in occurs it will never disappear completely.
If your problem is not solved
Turn your TV off and then on again once.
Never attempt to repair a defective TV yourself.
Check with your dealer or call a TV technician.

cleaning the screen.
When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like chamois soaks.
Do not use acetone, toluene and alcohol because they cause chemical damage. Do not use liquid cleaners or aerosol cleaners.Wipe
off saliva or water drops as soon as possible.Their long time contact with the screen causes deformations and color fading.
Plasma display characteristics
This Plasma display is designed to be used at altitudes up to 6562 ft above sea level (and/or local air pressure equal or above
800 hPa). Operating this set at higher altitude (lower air pressure) is possible. However, at high altitudes (or local air pressure equal
or below 800 hPa) the picture on this display may become unstable and picture performance can deteriorate. In addition, the plasma
display may produce a humming sound in these conditions.
These possible adverse effects relate to the altitude and are common of all plasma displays. Once the set is brought below aprox
6562 ft (and/or local air pressure equal or above 800 hPa) its function will most likely return to normal.
Note:Transportation at high altitudes has no negative effect on the set or picture performance.
How to dispose of batteries?
The batteries supplied do not contain the heavy metals mercury and cadmium. Nevertheless in many areas batteries may not be
disposed of with your household waste. Please ensure you dispose of batteries according to local regulations.
