Battery Status

The colour of the blinking indicates the current mode. You can change the mode as described in “Connecting the Tecla Shield DOS” section, but 
first, you will want to decide which mode is right for you.  Please refer to the table below for a short description of each of the modes.  For 
detailed instructions on how to use each mode, please refer to the corresponding section of the guide.

battery indicator.


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.


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 specific 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 first turn on your Tecla Shield, the status indicator light will start to blink.

Connecting the Tecla Shield DOS


If you are switching devices, unpair from 
your current device before connecting to 
the new one.


The - and + buttons are 
recessed into the case to 
prevent accidental selection.  
It is easiest to select them 
using small pointed objects 
such as a 1/8” switch plug or 
a key.
