You may select the time period, in seconds, in which the Menu will "Time Out" while inactive and clear the screen. It is good to have a "Time Out" to save the screen from burning in an image left on too long.
If the screen goes blank because of the menu timeout, it is recommended that you press an arrow key. This will prevent you from starting a process that pressing the <ENTER> or another key might start.
The minimum number of seconds for the Menu Timeout is 60 seconds (1 minute).
