How can I change the brightness of a ti-89 calculator?

I ran a downloaded program and it changed the screen to all black. When tilting it, I can still somewhat see the screen. The calculator is on and still works. I think only the brightness is the problem. How can I change the brightness level back? Thank you.

Press the green button (beneath 2nd) and then the - sign to make it lighter (or the + to make it darker).
