Adjusting the Display Contrast
You can adjust the display contrast to suit your viewing angle and lighting
conditions. As you change the contrast setting, a number from
0 (lightest)
to 9 (darkest) in the top-right corner indicates the current level. You may
not be able to see the number if contrast is too light or too dark.
Note: The TI-83 Plus has 40 contrast settings, so each number 0 through 9
represents four settings.
The TI-83 Plus retains the contrast setting in memory when it is turned
off.

2. Press and hold † or } , which are below and above the contrast
