About the indicators

CHARGE indicator (orange)

Turns off The speaker has completed charging.
Lights up The speaker is being charged.
Flashes slowly The built-in battery is running at less than 20% and needs to be charged. In this state, the speaker cannot supply power to other devices.
Flashes 3 times and turns off If the CHARGE indicator flashes 3 times and goes off when you turn on the speaker, the built-in battery is empty and needs to be charged.

Note

  • As long as the speaker is connected to an AC outlet by the AC adaptor (supplied), 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.

  • If you use the speaker at a loud volume for a long period of time, the remaining power of the rechargeable built-in battery will decrease even while the speaker is connected to an AC outlet by the AC adaptor. This may decrease the speaker volume but 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 AC adaptor, and then let the battery charge itself once again.
