Initializing the speaker
If the speaker fails to operate successfully after you restart it, initialize the speaker to resume its default settings.
While the speaker is turned on, touch and hold 
(play) and MEGA BASS on the speaker until the speaker turns off (5 seconds or more).
The speaker is initialized. Settings such as volume, etc., are restored to the default settings, and all pairing information is deleted.
Note
-
The speaker cannot be initialized while the power is off.
