Avaz supports switch scanning via iOS Settings for iOS version 7 and above.


In iOS 9, there is a new feature for Single Switch Step scanning. With this mode, the user moves from item to item on the screen by activating their switch. When the user reaches a desired item on the screen, they stop activating their switch for a predetermined dwell time and then the item is automatically selected.

Scanning modes now include three options:

› Auto Scanning

› Manual Scanning

› Single Switch Step Scanning


To access the scanning modes, go to Settings App > General > Accessibility > Switch Control > Scanning Style.


First set up the Scan mode using iOS settings and then open Avaz.
