This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference with radio communications. However, there is
no guarantee that interference will not occur in a particular
installation.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, you can try to correct the interference by one
or more of the following measures:
¦ Reorient or relocate the receiving antenna.
¦ Increase the separation between the equipment and receiver.
¦ Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
¦ Consult the dealer or an experienced radio/television technician
for help.
Caution:
Any changes or modifications to this equipment not
expressly approved by Texas Instruments may void your authority to
operate the equipment.

What’s New?
TI developed the Advanced Mathematics
Software Version 2.0 to enable
downloadable calculator software
applications for the
TI
-
89
and
TI
-
92 Plus
.
For details, refer to:
Chapter 21 and 22
Advanced Mathematics Software Version 2.0 is an infrastructure
enhancement of the current Advanced Mathematics Software
Version 1.xx. It has all the features of Version 1.xx. The improved
infrastructure enables multiple downloadable calculator software
applications, language localization. This enhancement also provides
your new
TI
-
89 / TI
-
92 Plus
with
maximum reapportionment of the
over 702-KB Flash memory between user data archive and calculator
software applications.
All previous
TI
-
89
and
TI
-
92 Plus Modules
can be upgraded to Version
2.0. However, on some
TI
-
89
and all
TI
-
92 Plus Module
units, the user
data archive can only occupy a maximum of 384-KB of the over 702-
KB Flash memory shared with calculator software applications.
You can download Advanced Mathematics Software Version
2.0 to your computer from the TI web site at
education.ti.com
,
then transfer it to your TI
-
89 / TI
-
92 Plus using the
TI™ Connect
or
TI GRAPH LINK™
software and a
TI-GRAPH LINK
cable. The Advanced Mathematics Software is free from the TI
web site at
education.ti.com
.
The
TI
-
89 / TI
-
92 Plus
can be localized into
other languages. These free applications
translate prompts, error messages, and
most functions into one of several
languages.
For details, refer to:
Chapter 1
The improved user interface allows folder collapse/expand and
expands the
CATALOG
menu to include application functions and
user-defined functions.

The
TI
-
89 / TI
-
92 Plus
uses Flash technology,
which lets you upgrade future software
versions without buying a new calculator.
For details, refer to:
Chapter 22
As new functionality becomes available, you can electronically
upgrade your
TI
-
89 / TI
-
92 Plus
. Future software versions include
maintenance upgrades that will be released free of charge, as well as
new applications and major future upgrades that will be available for
purchase from the TI web site.
To download upgrades from the TI web site, you must have an
Internet-connected computer,
TI™ Connect or TI-GRAPH LINK™
software, and a
TI-GRAPH LINK
cable. You can also transfer the
product software (operating system) and Flash applications from
one
TI
-
89 / TI
-
92 Plus
to another using a unit-to-unit cable, provided
that the receiving calculator is also licensed to run that software.
New to the
TI
-
92 Plus
is the custom menu feature that lets you create
your own toolbar menu. A custom menu can contain any available
function, instruction, or set of characters. The
TI
-
92 Plus
has a default
custom menu that you can modify or redefine.
