Initializing the speaker
If the speaker still does not work properly even after resetting, restore the speaker to the factory default settings by initializing it.
With the speaker turned on, press and hold the - (volume) button and the(power)/PAIRING button at the same time for more than 5 seconds until the speaker turns off.
The speaker is initialized. Settings such as volume, etc., are restored to the factory default settings, and all pairing information is deleted.
The speaker cannot be initialized while the power is off.
