Activation
When your switches are connected to your Grid Pad, you can
decide how they act within Grid 3. You can choose between
Switch Scanning, Switch elimination and Switch joystick.
Open Settings – Access – Switches and select the method you
would like to use from the drop-down box. Tap Activation to
configure your chosen method.
Switch scanning
Switch scanning highlights groups of cells in turn to locate the cell
that you want. This method highlights and scans through the cells
in your grid in a linear fashion.
You can choose to start with rows or columns. Activate your switch
to select the row or column you want, and then scan through that
row or column until you reach the desired cell. Activating your
switch again will then select that cell.
