Panasonic TH-50PZ80Q Quick Start Manual page 49

You can enjoy your home theater by connecting a Dolby Digital (5.1 channel) decoder and "Multi Channel" amplifier to the DIGITAL AUDIO OUT terminals.
Caution
Depending on your DVD player and DVD-Audio software the copyright protection function may operate and disable optical output.
External speakers cannot be connected directly to PROG OUT terminals.
When an ATSC channel is selected, the output from the DIGITAL AUDIO OUT jack will be Dolby Digital. When an NTSC
channel is selected, the output will be PCM.
See pages 40-41 for more information.
Do not display a picture in 4:3 mode for an extended period, as this can cause
"Image retention" to remain on either or both sides of the display field.
To reduce the risk of such "Image retention", change the brightness of the side bars.
See pages 26-27 for more information.
The side bar may flash (alternate black/white) depending on the picture. Using
Cinema mode will reduce such flashing (See below).
Scrolling bar: To prevent "Image retention", scrolls white horizontal bar from top to bottom on a black
screen.
Press any key except the POWER key to return to previous screen.
You will return to the previous screen if any key operation has not been performed for 15 minutes.
