Speech and Tone Mode

Speech and Tone modes, press and hold the Orion
Shift

Orion announces which mode you are in.
When using Speech mode, the coordinates are announced as the user navigates
through a graph. The following factors determine what is announced:
If the coordinates are turned off in the TI-84 Plus
Format

displayed on the screen, and therefore, will not be announced by the Orion.
The
Format
menu is accessed by pressing the

Zoom
key,
which is the middle key of the five function keys directly below the screen.
