Updating The Handheld Operating System; What You Need To Know - Texas Instruments TI-Nspire CX Getting Started Manual

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 web site (education.ti.com). You can update the operating
system (OS) on TI-Nspire™ handhelds using a computer and the
following software:
• TI-Nspire™ Teacher Software
• TI-Nspire™ Student Software
• TI-Nspire™ CAS Teacher Software
• TI-Nspire™ CAS Student Software
• TI-Nspire™ Navigator™ 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. See Memory and file management
for more information about restoring memory.
• 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.
Warning: Upgrading the operating system will delete all TI-84
applications and files. 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.
