The calculator permanently stores some values you enter;
others are retained only while you are using a particular
model. INS %, TAX %, DEBT %, INC %, TAX&INS$, and the
TVM values are stored permanently until you clear them,
change them, or remove the batteries.
Values in the other models share temporary storage space.
To prevent conflicts, only one temporary model can be
active at a time.

Entering a value into a temporary model makes it the
active model. If the model was not already active, the
remaining values are set to their defaults.
•
The model remains active until you store a value in
another model or perform a TVM calculation.
•
While a model is active, you can store its values to
memory or to the TVM values.
•
Attempting to use

A set of worksheets based on these models is enclosed to
use when working with clients. For most of the examples
in this book, a completed worksheet is included after the
keystroke solution to show how a worksheet can be used.
You may copy the worksheets for your personal use with
clients and customers. However, the worksheets may not
be reproduced in any other publication without the written
consent of Texas Instruments.
