CAUTION:

Symptoms Check

Some parts of the screen

do not light up.

The plasma TV panel is manufactured using an extremely high level of precision technology,

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

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.

During DVB teletext, radio service or menu display, the level of the contrast will decrease

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.
