Changing batteries in Casio Graph 35+ calculators without losing programs

Hello,

With my final exams approaching and my Casio calculator displaying "low battery, replace" for quite a while now, I'm hesitant to change them because I have a lot of formulas and programs stored in this calculator, and I really don't want to re-enter everything!
Do you have a way to change the batteries and keep all the programs in the calculator intact?
Thank you for your response!

Configuration: Windows 8 / Internet Explorer 10.0

    Indeed, you can remove your batteries without any worries. However, if you remove all 4 batteries and the flat battery at the same time, then you will have a nasty surprise. If you want to change the flat battery, do not remove the other 4 batteries!

      So basically, to avoid losing the programs when changing the batteries, you either need to change all 4 AAA batteries and leave the flat battery, or change the flat battery and leave the 4 AAA batteries, but above all, do not remove them at the same time?
