Lit Battery charging is in progress.

Note

  • As long as the speaker is connected to an AC outlet by a USB PD compatible AC adaptor, 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 PD compatible 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 PD compatible 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 a battery charging 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.
