Does anyone know the exact function of the red LED. The unit does not work for me and the LED behaves strangely. When it was working correctly, I expected it to light up according to the reception signal from the IR-FB, but it does not.
When plugging the mini-USB into the mains adapter without the ext. LEDs, the red LED lights up brightly. When the external parts are plugged in, it goes out more and more?
