Pressing the 

2nd

 key followed by the 

Quit

 key will take you to the Home 

screen regardless of the current active screen (Trace or Graph mode). This is 
announced to you. 

SonoGraph 

SonoGraph refers to the announcement of the graphs in the form of audible tones. 
SonoGraph is applicable only when Tone mode is selected and the active screen on 
the TI-84 Plus is in Trace mode. Tone mode is when each plotted point of an equation 
is made audible with a tone corresponding to its Y-coordinate. As you navigate (trace) 
the plotted graph of the equation, tones are issued for each point. Alternately, the 
entire graph for an equation can be heard by pressing both Orion Playback 

Pref.

 key 

and the Shift 

Shift

 key together. 

Details are as follows: 

 

The frequency of the tone generated corresponds to the Y-coordinate values of 
the plotted points of an equation. * The balance between the left and right 
speaker represents the x coordinate value. (The left-most point plays only in the 
left speaker. As x increases, 

 

The duration of the tone played for each point can be adjusted from the 
Preferences menu. The default setting is 1 second. 

 

For negative values of the Y-coordinate, white noise is mixed with the tone. 
This setting can be changed in Orion Preferences. 

 

For playback of the entire equation, tones are generated in sequence starting 
from the minimum X-coordinate value to the maximum X-coordinate value; the 
frequency of the tone corresponds to the Y-coordinate value of each point. 

 

If you navigate to a coordinate value outside of the visible screen area, a tone 
will not be generated. Instead, the coordinates are announced in speech format 
regardless of the mode selected. 

 

Regardless of the output mode (tone or speech), pressing the Orion 
Repeat 

Toggle Mode

 key always announces coordinates in speech format. 

 

If the previous operation on the TI-84 Plus was switching equations (switching 
between graphs), pressing the 

Repeat

 key results in speech announcement of 

the active equation along with the coordinate values. 

 

While graphs are being plotted on the TI-84 Plus screen, the calculator is 
"busy" and will not accept additional inputs. This is indicated with a series of 
short beeps, until plotting is completed. 

Y-Value Corresponding to X-Value in Trace Mode
