Using the System menu

Changes to system options are typically made only once. If your system operates as you want it to, there may be no need for any changes. In some cases, however, changes are required to make the system fully compatible with the installation options you have chosen.

Viewing and using the System menu

Unlike the source Settings menus, the System menu only appears on your TV screen.

Turn on your TV and select the correct TV input to view video from your 3∙2∙1 system.

on your remote, press the system button. the system menu appears with "audio" options selected, showing a list of the audio options that can be changed. entering the system menu will cause any dvd or vcd to pause.

on your remote, use the arrow buttons on the navigation pad to move around within the system menu, and press enter to select an item. any item that you select will then be highlighted in yellow within the menu.

at any time, you can press exit to leave the menu.


These options affect the way the system sounds in your home.

video black level
  • default setting: normal (option: extended)
  • normal is the screen black level generally appropriate for most tvs.
