  • If the charge indicator flashes 3 times when you turn on the speaker and then the speaker turns off, the rechargeable built-in battery has run out of power. Charge the speaker.

Note

  • As long as the speaker is connected to an AC outlet by a USB AC adaptor (commercially available), the speaker's built-in battery is capable of charging itself even while the speaker is turned on.

    Depending on the usage of the speaker, however, it may take a long time before charging completes. It is recommended that you turn off the speaker before 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.

  • If the ambient temperature is extremely low or high, the built-in battery will stop charging itself for safety reasons. It may also stop charging if charging continues for a long period of time. If such a case occurs, bring the temperature up or down to an operating temperature between 5 °C and 35 °C (41 °F and 95 °F), disconnect and connect the USB cable, and then let the battery charge itself once again.
