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.

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.

You will then need to replace or recharge the batteries before downloading the OS.
