Lightening and Darkening the TI – 83 Calculator Screen

To begin with, turn your calculator on by pressing the ON key which is located in the lower left hand corner of the calculator. If the screen of the calculator is too light, then press 2nd key and then the up arrow key. If the screen is still too light to read, then repeat the process of pressing the 2nd key and the up arrow key until the screen is dark enough to read comfortably.  If the screen is too dark, then press the 2nd key and the down arrow  key. If the screen is still too dark to read, then repeat the process of pressing the 2nd key and the down arrow key until the screen is light enough to read comfortably.  As you are pressing the sequence of keys (the 2nd key and either the up arrow or the down arrow  key), a number will flash in the upper right corner of the calculator screen. The number indicates the battery level of the calculator. If the battery level is 8 or 9, then you need to replace the batteries in the calculator. Your calculator requires 4 AAA batteries. The batteries should be changed one at a time if you have programs in your calculator.
