Unable to turn on the speaker or the speaker suddenly turns off

  • The rechargeable built-in battery may be empty or running low. Connect the speaker to an AC outlet with a USB AC adaptor (commercially available) for battery charging.

  • Depending on the type or specifications of the USB AC adaptor, if you use the speaker at a loud volume, the remaining power of the rechargeable built-in battery may decrease or the speaker may turn off even while the speaker is connected to an AC outlet by the USB AC adaptor. This, however, does not indicate a malfunction. If such a case occurs, turn off the speaker and let the battery fully charge itself before you use the speaker.

  • The Auto Standby function may have been activated. Turn off the Auto Standby function.
