In addition to the User's Guide, there is an e-mail list th at discusses the Orion TI-
30XS. To subscribe, send an e-mail to [email protected]. APH
customer support and developers and interested, knowledgeable users
exchange information here. The e-mail list is a great place to get usage tips, ask
questions, or make suggestions.
For the purposes of this guide, the standard TI-30XS MultiView™ Scientific
Calculator from Texas Instruments Incorporated is referred to as the TI-30XS.
The Orion TI-30XS MultiView™ Talking Scientific Calculator is referred to as the
Orion TI-30XS.
In order to make this document accessible for all users, we indicate keys on the
TI-30XS portion of the calculator with a bold font. For visual and audio
clarification purposes, we also use brackets around the words or symbols for a
particular keys, 2nd functions, or menu items when necessary. For example, the
key marked "sto right arrow" (store) is designated as [sto right arrow] and the
2nd function marked "right arrow %" is designated as [right arrow %].
Everything within the brackets is one key press.
If using the NVDA screen reader, it is recommended that you change the default
setting from "read some punctuation" to "read most punctuation" for the best
listening comprehension of this guide.
