Note!
To save battery power all LEDs are off during normal operation, even if the device is
communicating or joining the network. The LEDs only light up after start up or while
pressing the buttons.
When the pushbutton is pressed shortly (0.2 s ... 5 s), the three LEDs indicate the status of
the adapter (see chapter 6.1.2).
