Calculators Ti-89 help

  1. Sep 16, 2006 #1
    I can't even use the calculator. When I turn it on there are clear bars on the bottom and it covers it up so I can't exactly see what I typed in and to see what the answer is i have to keep pressing enter til it's pushed up enough...... I can't see graphs either at that bottom part.

    I tried googlging but it went nowhere.

    did you adjust the contrast?

    Press green button then + or -

    I'm not sure what you're describing. You could try restarting by holding diamond-left-right-on. This clears your RAM, so archive anything you want to save.
