The LED on my Xeo speaker does not light up.

Check whether the speaker is switched on, with the main switch at the rear, and that it is connected to a power outlet.

If only the red LED lights up, but not the blue LED, please contact your Dynaudio Xeo dealer.

The Xeo Transmitter / Xeo Hub / Xeo Connect must also be connected to the power by a USB cable or with the 5V plug-in power supply.
