Fields to the right of the listed options contain settings or values. The settings and values that you can change are brighter on the screen. All other settings and values are set by the computer and cannot be changed. When <Enter> appears to the right of an option, press <Enter> to access a pop-up menu of additional options.
- Key functions – A line of boxes across the bottom of all system setup screens that lists keys and their functions within the system setup program.
