receiving unit.

Upgrading the Operating System

You can upgrade the OS on your TI-Nspire™ CAS handheld using your computer and TI-Nspire™ Computer Link Software. You can also transfer the OS from one handheld to another.

OS upgrade operations do not delete user documents. If there is not enough room on the receiving handheld for the upgrade, the sending handheld is notified. The only time documents can be 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 your important documents and folders before installing an updated operating system.

See the important information below concerning batteries before performing an OS upgrade.

Important Operating System download information

It is always a good practice to install new batteries before beginning an OS download.

16 Getting Started

When in OS download mode, the Automatic Power Down 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 the batteries with new batteries before downloading.

(APD)

Where to get Operating System upgrades

For up-to-date information about available OS upgrades, check the Texas Instruments Web site at http://education.ti.com.

You can download an OS upgrade from the Texas Instruments Web site to a computer, and use a USB computer cable to install the OS on your TI-Nspire™ CAS handheld.

For complete information, refer to the instructions in the chapter on TI-Nspire™ Computer Link Software.

Backing up files to a computer

Use the TI-Nspire™ Computer Link Software to back up the contents of your handheld to a computer. TI-Nspire™ Computer Link Software is available on the product CD that came with your handheld.

Resetting the memory

The Reset button on the underside of the handheld resets all memory. When resetting all memory on the TI-Nspire™ handheld, RAM and Flash memory is restored to factory settings. All files will be deleted. All system variables are reset to default settings.

Caution: Before you reset all memory, consider restoring sufficient available memory by deleting only selected data.

To reset all memory on the handheld, follow these steps.

1. Use a paper clip or ball point pen to press the Reset button on the underside of the handheld.

2. Hold for three seconds, and release.
