tecla-e is also compatible with Samsung devices that have the Universal Switch accessibility feature. Check if your devices is compatible by going to Settings> Accessibility> Dexterity and Interaction and see if the Universal Switch feature is available.
With the tecla-e ready for connection and the switches connected to it, follow the steps below to set up your Android device with Universal Switch.
. Pair your tecla-e: Go to Settings > Bluetooth.
2. Turn on your tecla-e by sliding the 3-way Power switch to the middle position. To put your tecla-e in pairing mode, slide & hold the blue power switch to the gear position for 3 seconds, at which point the tecla-e will make a pairing sound.
3. With Bluetooth enabled, you should see the tecla-e listed under Available devices as tecla-e XXXX (where XXXX is a random sequence). Click on it. After a few seconds, tecla-e XXXX should be under Paired Devices and appear as Connected.
. Set up a Smart Lock: Once the tecla-e is connected, you can set it as a trusted device. This will keep your device unlocked as long as the tecla-e is connected to it. If you have a screen lock type (i.e PIN, Pattern, Password), go to Settings > lock screen and security > Secure lock settings > smart lock. Enter the screen lock type that your phone has set up. Then select Trusted devices > Add Trusted Device > Bluetooth. Select tecla-e XXXX as your trusted device.
5. Set-up Universal Switch: Go to Settings > Accessibility, then select Dexterity and Interaction > Universal Switch. Click on Settings.
6. Assign your switches to actions: If you are using single-switch access, make sure Auto Scan is on. To set-up your switch Go to Switches > Add a Switch.
7. Select Accessories. You will be prompted to press your switch at this point. Press a switch connected to the tecla-e. In the New Switch pop-up window write the name of the switch and press Save.
8. If you are using a single switch (or you are using more than one switch, but this is your main selection switch), choose the “Select Item” action. Check the Note section below for a brief description of other possible switch actions that you can assign to switches. The Recommended Configurations (table 1 & 2) may also be helpful for assigning switch actions.
9. Repeat steps 4-6 for all your switches. For possible combinations check the Recommended Configuration section below.
10. Select item mode scanning: on the Universal Switch settings page, go to Scan Method and Select Row.
11. Ensure On-Screen Keyboard is shown: Go to System > Language and input > Default Keyboard. Make sure you have Samsung Keyboard as your selected keyboard.
12. Enable Switch Access: Go back to Universal Switch, and activate Switch Access by clicking on the on/off control. At this point, you should be able to control the Android using the Switch Control through the tecla-e. When you pressed any of your assigned switches you should see a frame around the user interface.
