Restoring the default settings of the speaker (Initialization)

With the speaker turned on, touch and hold the(Play/Pause) button and the(Volume -) button simultaneously for more than 4 seconds. When the speaker takes the instruction, the BLUETOOTH,(Music Service), and AUDIO IN indicators light up at the same time. These three indicators go out in a while to indicate completion of the initialization process, and then the speaker restarts.

When the speaker is initialized, the pairing information and the network settings of the BLUETOOTH devices are deleted and all the speaker settings are restored to the factory default setting values.
