however, sometimes some parts of the screen may be missing picture elements or have
luminous spots. This is not a malfunction.
After-images appear
ABCDEF
ABCDEF
Do not allow a still picture to be displayed for an extended period, as this can cause a
permanent after-image to remain on the Plasma TV.
Examples of still pictures include logos, video games, computer images, teletext and
images displayed in 4:3 mode.
With no signal present, and without any user operation, the Panasonic screensaver will
appear automatically after a few minutes to prevent image retention.
Note:
The permanent after-image on the Plasma TV resulting from fi xed image use is not an
operating defect and as such is not covered by the Warranty.
This product is not designed to display fi xed images for extended periods of time.
Sleep Feature
If the set is not switched off when the TV station stops transmitting, it will automatically go to standby mode after 30
minutes. This function will not operate when this TV is in AV mode.
Notes:
• External surfaces of the unit may become hot during operation. But this is completely normal.
• See label on the base of this equipment for ratings and other information.
