Factory reset

  1. Power off the device.
  2. Power on the device.
  3. Wait until all LEDs light up and turn off again, then press the Service button.
  4. Keep the Service button pressed until all LEDs light up, then release the button.
    All LEDs go off, the device restarts.
  5. Wait until the device has fully started – unconfigured (green RUN LED and red SVC LED are flashing)
