The TI-89 Titanium is no ordinary calculator. Texas Instruments designed it as its top-of-the-line and most powerful graphing calculator. The Titanium device builds on the success of the early TI-89 calculator to include advanced features like extra internal memory and pre-loaded calculator applications. Discover how to setup and start using your TI-89 Titanium calculator to unleash its full potential and make use of all of its features.

1. Load the TI-89 Titanium's batteries. Push and slide down the battery compartment cover on the back of the calculator. Insert four AAA-sized batteries, included with all new TI-89 products, into the compartment and replace its cover.
2. Power on the device. Press its "ON" button. A progress loading bar will appear on the screen. Once its loaded, you'll be greeted with the TI-89's application desktop.
