self-scanning and inverse scanning modes. Connect your switch to the Switch
Port 1 (SP1) on the Tecla Shield to start using immediately.

inverse scanning modes. It is also possible to use two switches in step-scanning
mode by changing the corresponding switch actions with the Configure switch
actions setting in the Tecla Access Settings app. By default, a switch connected
to Switch Port 1 (SP1) on the Tecla Shield will activate the highlighted option
while a switch connected to the Switch Port 2 (SP2) on the Tecla Shield will
cancel the last selection (when the full keyboard is shown).
· Multiple switches (3+) –Tecla Access can be used with up to 4 switches
connected to the ECU port. By default, switch 1 activates a selection, switch 2
cancels the last selection, switch 3 moves to the next item in keyboard and

restored at any time with the Configure switch actions setting in the Tecla
Access Settings app.
