3.1a.

If this screen is shown, tap Enroll with EloView if you want to use the device with EloView, or tap Android Home Mode if you want to install Qmatic Kiosk or Qmatic Display from .APK (without using EloView).

3.1b.

If this screen is shown, tap START to start the device in Android Home Mode.
There are usually a bunch of configuration steps required after tapping the START button, see next section.

Note:
If you want to connect this device to EloView, then you first need to go through the procedure to start the device in Android Home Mode, and then go to Android settings to reset the device to EloView.

If the blue screen with START button is shown when starting up, there are usually a few more configuration steps before the Android desktop is shown.

Note that these may differ depending on various factors such as Android version etc.
