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.
TI-Nspire™ Handheld Keys Use the TI-Nspire™ Touchpad as you would a laptop touchpad. You can also press the outer edges to move right, left, up, and down. d Removes menus or dialog boxes from the screen. Also stops a calculation in progress. c Turns on the handheld. If the handheld is on, this key displays the home screen. » ~ Opens the Scratchpad for performing quick calculations and graphing. Opens the Document menu. e Moves to the next entry field.
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.

Connecting Handhelds and Transferring Files This chapter describes how to connect one TI-Nspire™ handheld to another, how to connect handhelds to a computer, and how to transfer files between them. The TI-Nspire™ handhelds have a USB port that enables connectivity with another TI-Nspire™ handheld or with a computer. Note: When using the TI-Nspire™ TI-84 Plus keypad, you can connect with another TI-Nspire™ handheld using the TI-Nspire™ TI-84 Plus keypad or a TI-84 Plus using the USB port or the I/O port.
The TI-Nspire™ handheld USB port is located in the center on the top of the TI-Nspire™ handheld.
