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.
