Web Browser
The Web Browser supports HTML5 pages.
You can browse the internet much like you do with a PC.
A cell phone may be used to detect the TV’s
Bluetooth transmission. The name “Panasonic
Viera” is displayed on the cell phone when the 3D

capable of discovering the Panasonic Bluetooth
signal. The self-check procedure on the left is
most reliable.
To access the self-check screen, simultaneously
hold down the Volume Down button of the TV
