Getting Started with TI-Nspire™ CX II Handhelds

The TI-Nspire™ CX II and the TI-Nspire™ CX II CAS are the newest handhelds in the TINspire™ 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 the following TI-Nspire™ CX II handhelds:

• TI-Nspire™ CX II / TI-Nspire™ CX II CAS

• TI-Nspire™ CX II-T / TI-Nspire™ CX II-T CAS

• TI-Nspire™ CX II-C CAS

• TI-Nspire™ CX II EZ-Spot

While they operate identically in many ways, there are a few distinctions. If there are differences between the Numeric, Exact Arithmetic, or CAS handhelds, it is pointed out and the appropriate operation is described.

About Math Modes

TI-Nspire CX II handhelds perform calculations in one of three modes: Numeric, Exact Arithmetic, or Computer Algebra System (CAS).

Numeric mode supports results in terms of floating point numbers, integers, and

stacked fractions only.

Exact Arithmetic mode supports results in terms of floating point numbers, integers,

stacked fractions, p, e, radicals ‡, and other constants such as ln(5) and sin(2).

CAS mode supports the same results as Exact Arithmetic as well as symbol

manipulation such as x+x, and CAS functions such as symbolic factoring, solving equations, limits, and indefinite integration.

The math modes that are available will depend on which TI-Nspire CX II handheld model you have:

• Move to a point and hover to move the trace cursor to that point.

• Press ¡or¢ to move from point to point on the function’s graph. The

coordinates of each point traced are displayed.

• Press £or¤ to move from one plot to another. The point’s coordinates

update to reflect the new location of the trace. The trace cursor is positioned on the point of the new graph or plot with the closest x value to the last point identified on the previously traced function or graph.

• Type a number and press · to move the trace cursor to the point on the plot

with independent coordinates nearest the typed value.

• Create a persistent point that remains on the graph by pressing · when the

trace point reaches the point you want to label. The point remains after you exit Graph Trace mode.

Connecting the TI-Nspire™ Handheld to a Computer

1. Firmly insert the mini-USB end of the cable into the port at the top of your handheld.

2. Firmly insert the USB end of the cable into the USB port of the computer.

Transferring Files between Handhelds

You can send documents, Operating System (OS) files, and folders to another TINspire™ handheld.

Note: TI-Nspire™ CX handhelds must be running v4.5.1 or later of the OS in order to

transfer to or from TI-Nspire™ CX II handhelds.

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.

Sending a Document or Folder to Another Handheld

1. Ensure the two handhelds are connected.

2. Open the My Documents file browser and navigate to the file or folder you want to transfer.

3. Press the 5 and 6 keys on the Touchpad to highlight the document or folder you want to send.

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 TINspire™ 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.

▶ To check the status of the rechargeable battery in TI-Nspire™ CX II handhelds, press

c 5 4 to open the Handheld Status dialog box.

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.

handheld and you cannot transfer the OS on an Exact Arithmetic or CAS handheld to a non-Exact Arithmetic or non-CAS handheld. The operating systems are not the same and are not interchangeable.

To transfer the OS from one handheld to another:

1. Ensure any open documents on the receiving handheld are closed.

2. Connect the two handhelds using a USB mini-A to mini-B USB cable.

3. On the sending handheld, select Browse from the Home screen.

4. Press b, and then select Send OS. On a TI-Nspire™ handheld, press b.

• If Yes is not selected within 30 seconds, the handheld automatically responds

with No, and the transmission is cancelled.

• It is important to save and close all open documents before performing an OS

Upgrade. Continuing with an OS Upgrade on a handheld with an open, unsaved document will cause the loss of that data.

6. While the upgrade is in progress, the following messages are 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.

Updating the Handhe ld Ope rating System 87

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.

Important:

• For each receiving handheld, remember to back up information as necessary and install new batteries.

• Be sure the sending handheld is on the Send OS screen.
