The screen on my calculator is crazy!

I've got a fx-9750gii Casio calculator, I've put in the right batteries, and when I turn them on, the screen appears crazy! When I press any button, the screen appears the same with unrecognizable images. I tried turning it off and back on, still the same. It clearly seems to have an error to the graphics: and I do not know how to fix it.

Please help!
