To start your Tecla Shield should be in 4-way Mode (blinking bright pink). If you are not sure how to change modes check here: Mode Change Instructions.
The 4-way mode takes advantage of VoiceOver, Apple’s built-in screen reading technology. The Vertical Navigation rotor option in VoiceOver provides 4-way switch-based navigation of the user interface.
This mode is designed for joystick or 4 or more switches and does not have the advanced features of Switch Control like gesture emulation. For most users we recommend using Switch Control, you can find the set-up instructions here:

To set it up:
1. Go to Settings > Bluetooth. With Bluetooth enabled, you should see the Tecla Shield DOS listed under Devices as TeclaShieldDOS-XXXX (where XXXX is a random sequence). Click on it. TeclaShieldDOS-XXXX should be under MY DEVICES and the status should change to Connected.
2. Go to Settings > General > Accessibility > VoiceOver. Make sure VoiceOver is On.
3. Scroll down to the Rotor option. Un-check all Rotor options except Vertical Navigation; it should have a check mark to the right, as shown below.
4. Start controlling your iPhone or iPad using your adapted switches or the driving control of your powered wheelchair
5. Enable triple-click Home shortcut (optional) to toggle between touch mode and switch-access mode at any time. Go to Settings > General > Accessibility > Accessibility Shortcut and select VoiceOver.
