When the CHARGE indicator flashes slowly in orange, the battery is running low and needs to be charged.

needs to be charged.
For customers in Europe, Asia and Latin America
The shape of the USB AC adaptor is slight different from the illustration and alternative plugs are supplied. Attach a plug
appropriate to your country/region to the USB AC adaptor beforehand.
Hint
A speaker that is in use can be charged if it is connected to an AC outlet, though the CHARGE indicator does not light up. In this case, it may take
longer to charge the battery than when the speaker is turned off depending on the conditions of use. Therefore, it is recommended that you turn off
the speaker when charging.
Note
When you use the speaker at a loud volume, the battery may run low even if the speaker is connected to an AC outlet. If you want to use the
speaker while charging, lower the volume of the speaker. Otherwise, turn off the speaker and charge the battery to its full capacity.
When you use the speaker at a loud volume for a long time, the battery may run low even if the speaker is connected to an AC outlet. As a result,
sound becomes low. This is not a malfunction. Turn off the speaker and charge the battery to its full capacity.
When you switch the power source between an AC outlet and battery by connecting/disconnecting the USB AC adaptor, the speaker may stop
sound output for a short while. This is not a malfunction.
The maximum power output will be lower when the battery is running low.
Even if you do not intend to use the speaker for a long time, charge the battery to its full capacity once every six months to maintain its
performance.
In an extremely cold or hot environment, charging stops for safety. Try charging the battery again within the operating temperature of between 5
°C and 35 °C (41 °F and 95 °F).
