You can upgrade the OS on your TI-89 Titanium using your computer. You can also
transfer the OS from one unit to another identical model (for example, from a TI-89
Titanium to a TI-89 Titanium or from a Voyage™ 200 to a Voyage™ 200).
Installing OS software resets all device memory to the original factory settings. This
means that all user-defined variables (in both RAM and the user data archive), functions,
programs, lists, and folders (except the Main folder) will be deleted. It is possible that
Flash applications could also be deleted. You should use TI Connect software to back up
your data to your computer before installing a new OS on your calculator.
See the important information concerning batteries before performing an OS upgrade.
