Updating The Handheld Operating System; What You Need To Know - Texas Instruments ti nspire cx Manual Book

Updating the Handheld Operating System

To take advantage of the latest handheld features and updates, download the latest
operating system files from the Education Technology website (education.ti.com). You
can update the operating system (OS) on TI-Nspire™ handhelds using a computer and
the following software:
• TI-Nspire™ CX Teacher Software
• TI-Nspire™ CX Student Software
• TI-Nspire™ CX CAS Teacher Software
• TI-Nspire™ CX CAS Student Software
• TI-Nspire™ CX Navigator™ Teacher Software
• TI-Nspire™ CX CAS Navigator™ Teacher Software
In the classroom, you can use the TI-Nspire™ Docking Stations to upgrade the OS on
multiple handhelds at the same time.
You can also transfer the OS from one TI-Nspire™ handheld to another or from one
TI-Nspire™ CX handheld to another. However, handheld operating systems are not
interchangeable. You cannot transfer a CAS operating system to a non-CAS handheld
and you cannot transfer a TI-Nspire™ handheld operating system to a TI-Nspire™ CX
handheld.

What You Need to Know

• If there is not enough room on the receiving handheld for the upgrade, a message
is displayed. For more information, see Memory and File Management.
• OS upgrade operations do not delete user documents. The only time documents
are affected by an OS installation is if the receiving handheld has a corrupted OS.
In this situation, documents may be affected by OS restoration. It is a good practice
to back up important documents and folders before installing an updated operating
system.
Upgrading the operating system will delete all TI-84 applications and files.
Warning:
Before installing an OS upgrade, you should use TI Connect to back up all TI-84
applications and files to a computer. You can copy them back to the handheld when the
OS upgrade is complete.
Before You Begin
Before beginning an OS download, ensure that batteries are at least 25 percent
charged.
