The TV's features are accessed through the on-screen menu
system. The Point and Select rule teaches you all you need to
know about navigating through the system.
To use the Point and Select rule:
1. PressMENU to bring up the Main Menu.
2. Use the MOVE arrows to point to a menu item.
3. Press MENU to select that item.
Menus take you to another menu or control panel. Control panels
do the work in the menu system: it's where you choose a setting,
enter a number, or adjust a level such as tint or brightness.
