Switch Scanning
As an alternative to directly selecting each button on the screen,
NOVA chat offers single switch and two switch scanning. To
access the options for customizing a scanning technique, choose
Menu
or > Settings > Input > Scanning.
Setting Description
Enable Scanning Turns scanning on or off. You must turn scanning on
to access the other settings.
Switch Access Defines the selection method (Touchscreen Only, One
Switch, One Switch + Touchscreen, or Two Switch),
and allows you to turn auto scanning on or off.
Auditory Prompts Defines audio feedback during scanning. You can set
the speaker or an earphone as the audio output device,
adjust earphone volume, turn a scanning beep on or
off, set a button prompt, and set the voice pitch and
rate.
Patterns Sets the scanning pattern to either linear or
row/column and turns scanning of the Speech Display
Bar and empty button areas on or off.
Scan Timing Defines the scanning speed and the number of rescans,
and turns activation delay and auto restart on or off.
Other Defines the color of the scanning cursor.
Configuring Switches
If external switches are required for a selection site, plug the
switch in either the switch A or switch B connector on the side
panel of the amplifier. Another option would be to use the
screen of the device as a switch.
You can choose to have scanning activate automatically, or you
can choose to either hold the switch or step to each location.
With Auto Scan off, a switch activation is required to move the
scan through each button, one at a time.
1. To enable scanning, choose Menu
or > Settings >
Input > Scanning > Enable Scanning.
2. Choose Switch Access > Switch Configuration.
