Note: To switch the audio source from B luetooth to USB, please stop music playback and disconnect the GO blu from the Bluetooth source. Connect the USB-C input (8) to the U SB audio source via a U SB cable and select the GO blu as the playback device.

To switch from USB to Bluetooth transmission, disconnect the GO blu from the audio device and reconnect the Bluetooth device.

The default setting of the phone does not allow charging of the GO blu (except in exclusive mode).

Tip: Exclusive mode is when the device outputs only the sound of the currently used application. Only a few applications have an exclusive mode setting; in general there is no difference to charging the GO blu between turning exclusive mode on or off. However some applications allow charging with exclusive mode on.
