Introduction
The TI-89 Titanium graphing calculator
This guidebook provides information about a powerful, advanced
graphing calculator available from Texas Instruments: the TI-89 Titanium.
Your TI-89 Titanium comes equipped with a variety of preinstalled
software applications (Apps) that have features relevant to many
different subjects and curriculums.
Using Flash read-only memory (ROM) for the TI-89 Titanium (4 megabytes
[MB] available), you can install additional Apps and increase the
capabilities of your calculator. Installing Apps and operating system (OS)
upgrades is like installing software on a computer. All you need is
TI Connect™ software and a TI Connectivity Cable.
The TI-89 Titanium graphical user interface (GUI) and configurable Apps
desktop make it easy to organize Apps into categories that you create.
Extend the reach of your TI-89 Titanium with accessories, such as the
Calculator-Based Laboratory™ (CBL 2™) systems, Calculator-Based
Ranger™ (CBR™) system, TI-Presenter™ video adapter, and
TI ViewScreenoverhead panel.
The CBL 2 and CBR systems offer static and real-world data collection.
Use the TI-Presenter video adapter to connect the TI-89 Titanium to video
display/recording devices, such as TVs, VCRs, video cameras, and
computer projectors. The TI ViewScreen overhead panel lets you project
an enlarged image of the TI-89 Titanium display so an entire class can
view it.
How to use this guidebook
We’ve added conventions to make it easier for you to get the most out of
this guidebook.
• Key symbols appear throughout the guidebook.
• Many keys can perform more than one function. To use secondary
functions, which are printed above the keys, you must first press 2,
j, or ¹. These extra functions are printed within brackets in this
guidebook.
For example, a procedure might include this key sequence used to
display a menu of special characters:
Press 2¿. (Press and release the 2key, then press the ¿
key, which is the second function of the «key.)

vi Introduction
• Key commands that require you to press and hold two keys at the
same time are indicated by the phrase press and hold. For example,
the instruction to darken the display contrast is:
Press and hold 8and tap «.
• Your graphing calculator uses menus to access many operations.
Menu options often can be selected using one of two methods. For
example,
Press „9:Trig
means that you can choose the Trig option first by pressing „and
then either pressing the 9key or pressing Das many times as
required to select Trig, and then pressing ¸.
The chapters in this guidebook include:
Getting Started – Offers students and educators in all curriculums a
quick overview of the basic operations of the TI-89 Titanium.
Previews – A set of short examples that include step-by-step procedures,
actual keystrokes, and sample displays.
Activities – A set of longer examples that shows how to solve, analyze,
and visualize actual mathematical problems.
Connectivity – How to link your graphing calculator to another
calculator or to a computer using either the USB or the I/O port, with
details about how to transmit variables and applications, and how to
upgrade the operating system.
Memory and Variable Management – How to manage variables
stored in your graphing calculator’s memory and in the data archive, a
protected area of memory separate from RAM (random access memory).
Technical Reference – Includes the syntax and action of each function
and instruction included in the operating system, an alphabetical listing
of operations, error messages, and other reference information.
The remainder of the product information is available in electronic form.
This comprehensive set of electronic chapters is included on the CD-ROM
that came with your TI-89 Titanium. This same information is also
available online as a free download at:
education.ti.com/guides

Getting Started
Initial start-up
Installing the AAA Batteries
The TI-89 Titanium uses four AAA alkaline batteries and a backup silver
oxide battery (SR44SW or 303). The backup batteries are already
installed, and the AAA batteries are provided with the product.
1. Remove the battery cover from the back of the calculator.
2. Unwrap the four AAA batteries provided with your product and
insert them in the battery compartment. Arrange the batteries
according to the polarity (+ and -) diagram in the battery
compartment.
3. Replace the battery cover on the calculator. The cover should snap
into place.
Turning on your TI-89 Titanium for the first time
After installing the batteries included with the calculator, press ´. The
Apps desktop appears.

2 Getting Started
Note: If your calculator initializes the preinstalled Apps, a progress bar
will appear with the message “Installation in progress . . . Do
not interrupt!” instead of the Apps desktop. To avoid losing Apps, do
not remove the batteries during initialization. (You can re-install Apps
from either the Product CD-ROM or education.ti.com.)
Adjusting the contrast
The Apps desktop
The Apps desktop is the starting point for operating your TI-89 Titanium.
Your installed Apps appear on the Apps desktop as icons organized in
categories for easy access. From the Apps desktop, you can:
• Open Apps.
• Select and edit categories of Apps.
• View all of the Apps installed on your calculator.
• View the full name of the highlighted App.
• View and edit the time and date.
• Check status line information.
• View split-screen mode information.

To return to the Apps desktop at any time, press O. The last category
selected appears with the last open App highlighted.
Turning off the calculator
Press 2®. The next time you turn on the calculator, the Apps
desktop appears with the same settings and memory contents retained.
(If you turned off the Apps desktop, the calculator Home screen appears.)
You can use either of the following keys to turn off the TI-89 Titanium.
Note: ® is the second function of the ´ key.
The calculator’s Automatic Power Down™ (APD™) feature prolongs
battery life by turning the calculator off automatically following several
minutes of inactivity. When you turn on the calculator after APD:
• The display, cursor, and any error conditions are exactly the same as
before APD.
• All settings and memory contents are retained.
Press: Description
2 ® (press 2
and then press ®)
Settings and memory contents are retained
by the Constant Memory™ feature.
• You cannot, however, use 2 ® if an
error message is displayed.
• When you turn the TI-89 Titanium on
again, it displays either the Home screen
or the Apps desktop (regardless of the
last application you used).
¥ ® (press ¥
and then press ®)
Similar to 2 ® except:
• You can use ¥ ® if an error message is
displayed.
• When you turn the TI-89 Titanium on
again, it will be exactly as you left it.

4 Getting Started
Note: APD does not function when a calculation or program is in
progress, unless a pause is specified in the calculation or program.
