Getting Started with the TI-Nspire™ CX Handheld

The TI-Nspire™ CX handheld and the TI-Nspire™ CX CAS handheld are
the newest handhelds in the TI-Nspire™ family of products. Featuring a
backlit color display and a slimmer form, the handhelds provide
touchpad navigation, dynamic graphing, and interactive computer
features.

The handhelds 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-color 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™ CX handheld and the TI-Nspire™
CX CAS handheld. While they operate identically in many ways, there are
a few distinctions. If the TI-Nspire™ CX 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 recognize, 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.

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.

Memory and File Management

The TI-Nspire™ CX Handheld comes equipped with 192 MB of memory.
Of the total memory, 128 MB is dedicated to Flash storage and 64 MB is
RAM. When the operating system is loaded, and as documents are
created and stored on the handheld, memory is used and you may find
that you need to free or restore memory after several months of use. If
there is insufficient memory on the handheld, use one of the following
options to restore space on the handheld:

• Delete documents and folders you no longer use.

• Back up files and folders to another handheld or computer.

• Reset the memory, which deletes ALL files and folders on the

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™ Teacher Navigator™ Software

• TI-Nspire™ CAS Teacher 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. 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.

Before You Begin

Before beginning an OS download, ensure that batteries are at least 25
percent charged.

Updating the Handheld Operating System 93

handhelds, press

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.

Finding Operating System Updates

For up-to-date information about available OS upgrades, check the Texas
Instruments website at education.ti.com.

You can download an OS upgrade from the Texas Instruments website to
a computer, and use a USB cable to install the OS on your TI-Nspire™
handheld. You will need an Internet connection and the appropriate USB
cable to download the updates.

Checking for Handheld OS Updates

When using TI-Nspire™ software, you can quickly determine if your
handheld OS is up to date when the handheld is connected to a
computer.

1. Open the TI-Nspire™ software and ensure the handheld is connected
to your computer.

2. In the Documents Workspace, click to open Content Explorer.

3. In the Connected Handhelds pane, select a connected handheld.
