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 the supplied AC power cord (mains lead) for battery charging.

  • The Auto Standby function may have activated. After about 15 minutes in certain circumstances, such as when the volume of the audio input is low, the power will automatically turn off. Raise the volume of the connected device for use, or set the Auto Standby function to off.
