Updating The Handheld Operating System; What You Need To Know; Finding Operating System Upgrades - Texas Instruments TI-Nspire CX II Series Handhelds Manualbook

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 Premium Teacher Software (v5.0 and later)
• TI-Nspire™ CX Student Software (v5.0 and later)
• TI-Nspire™ CX CAS Premium Teacher Software (v5.0 and later)
• TI-Nspire™ CX CAS Student Software (v5.0 and later)
• 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 II handheld to another. However, handheld operating systems are not
interchangeable. You cannot transfer an Exact Arithmetic or CAS operating system to a
non-Exact Arithmetic or non-CAS handheld and you cannot transfer a TI-Nspire™
handheld operating system to a TI-Nspire™ CX II 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 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.
Before You Begin
Before beginning an OS download, ensure that batteries are at least 25 percent
charged.

When in OS download mode, the Automatic Power Down™ (APD™) feature does not
function. If you leave your handheld in download mode for an extended time before
you begin the downloading process, your batteries may become depleted. You will then
need to replace or recharge the batteries before downloading the OS.
