  • Calculators:
    Casio Graph 25 Eii

Posted 29 September 2024 - 09:20 PM

Hi!

I just bought a new Graph 25+ EII calculator. However, when turning it on, it doesn't show the Main Menu, just the message "OSUpdate". There seems to be no way to get past this message. 

 

I didn't find anything relevant in the manual, neither on the internet.

 

Does somebody know how to solve this?

 

Thank  you!
