OS & Files
The operating system (OS) and add-ins give the calculator its functionality. For recent graphic calculators you can update the OS and replace add-ins that have been accidentally deleted.
Files, especially data, can be transferred to newer graphic calculators for analysis.
It is not possible to update the OS, use add-ins or transfer data to older graphic calculators or any scientific calculator.
Please choose the calculator below that you wish to update or transfer files to.
- fx-CG50
- fx-9860GIII
- fx-CG20
- fx-9860GII
