Please check the following if the speaker is not turning on:
- Make sure the AC adaptor is connected to the speaker and the AC outlet firmly.
NOTE: When using the speaker for the first time, you cannot turn the speaker on without the AC adapter connection since the speaker is set to reduce battery drain before shipment. Connect the AC adapter first, then press the POWER button to turn the speaker on.
- Charge the built-in battery.
- The speaker may not turn on if a system error occurs. To resolve this, push the RESET button on the rear side of the speaker to reset.
