Purple
iOS Classic
This mode uses Apple’s VoiceOver facility to access and control iOS devices. It works
in all iOS versions. This mode allows for linear scanning navigation (i.e., next item and
previous item) and can be used with a single switch all the way up to 4 switches.
This is the mode to access and control Android devices. It works in combination with
the Tecla Access app, available for free in the Google Play Store.
This mode is used with iOS “switch accessible” apps that use Space and Enter as switch
inputs. It can also be used with Mac and Windows computers in combination with 3rd
party scanning software.
White Switch Control
This mode works in combination with Apple’s accessibility feature called Switch
Control (available starting in iOS7 and OS X Mavericks). With this mode, you can
assign each switch to a specic action, such as “Select Item”.
Like the iOS Classic mode, this mode uses VoiceOver to navigate the device, but you
can move in four directions, as opposed to the linear navigation in the iOS Classic
mode. It is especially useful when using with a joystick or other multiple switches.
This mode works in combination with MouseKeys in Mac and Windows computers,
allowing the user to control the mouse pointer using multiple switches.
When you rst turn on your Tecla Shield, the status indicator light will start to blink.
