Getting Started with the TI-Nspire™
Handheld
The TI-Nspire™ handheld and the TI-Nspire™ CAS handheld are the
second generation handhelds in the TI-Nspire™ family of products. These
handhelds provide touchpad navigation, dynamic graphing and
interactive computer features.
The handheld and the TI-Nspire™ software share the same functionality,
enabling you to transfer class assignments from the handheld to the
computer or transfer documents to the handheld when you need to be
mobile. Start assignments at school, and then finish the work at home to
take advantage of the software’s full-colour display and easy-to-use
navigation. Use the software to download the latest software and
handheld operating system updates as they become available to ensure
you have the latest enhancements.
This guide covers both the TI-Nspire™ handheld and the TI-Nspire™ CAS
handheld. While they operate identically in many ways, there are a few
distinctions. If the TI-Nspire™ CAS handheld has additional functionality,
it is pointed out and the CAS operation is described.
About CAS
With CAS, or the Computer Algebra System, you can:
•
Perform both symbolic and numeric calculations.
•
Factor and expand expressions and solve for common denominators.
TI-Nspire™ CAS technology makes it possible to recognise, simplify and
calculate math expressions, preserving the symbols including variables
and terms such as “e” and p.
This ability to enter and view equations and expressions on screen as they
appear in textbooks is especially useful for step-by-step, arithmetic,
algebraic and calculus calculations.

Preparing the Handheld for Use
TI-Nspire™ handhelds are shipped with four alkaline AAA batteries and a
standard A male to mini B male USB cable. Handhelds can also be
powered using the TI-Nspire™ Rechargeable Battery or an approved wall
charger, which are sold separately.
Before using the handheld, either install the AAA batteries or install and
charge the TI-Nspire™ Rechargeable Battery (if purchased). You can also
connect your handheld to an external power source if you have the wall
charger.
Note: For more information about installing batteries, see Configuring

Transferring Files to and from Handhelds
You can send documents, Operating System (OS) files and folders to
another TI-Nspire™ handheld.
Rules for Transferring Files and Folders
•
You can transfer documents and OS files.
•
Operating systems are not interchangeable between different
handheld types. For example, you cannot transfer a CAS operating
system to a non-CAS handheld.
•
If a document with the same name as the one you are sending
already exists on the receiving handheld, the document will be
renamed. The system appends a number to the name to make it
unique. For example, if Mydata existed on the receiving handheld, it
would be renamed Mydata(2).
Both the sending and receiving handhelds will display a message that
shows the new name.
•
There is a 255-character maximum length for a file name, including
the entire path. If a transmitted file has the same name as an existing
file on the receiving handheld and the file names contain 255
characters, the name of the transmitted file will be truncated to
enable the software to follow the renaming scheme described in the
previous paragraph.
•
All variables associated with the document being transmitted are
transferred with the document.
•
Transmissions will time out after 30 seconds.
Caution: Some older TI-Nspire™ handhelds cannot receive folders; only
files. If you receive an error in sending to an older TI-Nspire™ handheld,
see Common error and notification messages.

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™ Teacher Software
•
TI-Nspire™ Student Software
•
TI-Nspire™ CAS Teacher Software
•
TI-Nspire™ CAS Student Software
•
TI-Nspire™ Navigator™ Teacher Software
•
TI-Nspire™ 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.
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.

displayed on the receiving and sending handhelds:
•
“Receiving OS. Do not unplug cable.”
•
“Sending OS. Do not unplug cable.“
7. After the transfer completes, the sending handheld receives a
completion message and you can unhook the cable. The OS is
automatically installed on the receiving handheld. During the
installation process, the “Installing OS <version number>” message is
displayed on the receiving handheld.
8. When the installation is complete, the “OS <version number> has
been installed. Handheld will now restart.” message is displayed. The
restart is initiated. If the sending handheld is still attached to the
cable, the successful transmission message remains displayed on that
handheld’s screen.
