Question about Texas Instruments TI-83 Plus Calculator
What would cause the calculator not to turn on. I just put in fresh batteries.
The batteries may be inserted incorrectly Should be +-+-.
The most common is that the screen is not dark enough: The calculator is on, but the user cannot see anything. The first things someone should verify are the two above.
If one wants to darken the screen one should proceed as follows.
Press the ON button (even if you cannot see the result)
1. Press [2nd] key and release it.
2. Press the [UPArrow] key , the one under [GRAPH], and release it.
3. Repeat Steps 1 and 2 in sequence until the screen darkens. One may have to repeat Step1, Step2, ...several times.
