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

If the CHARGE indicator flashes three times in orange and turns off when you turn on the speaker, the battery is

empty and needs to be charged.

For customers in Europe

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 to 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 before use.

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. If charging takes a long time, it also makes

charging of the speaker stop. Try to charge the battery again within the operating temperature of between 5 °C and 35

°C (41 °F and 95 °F).
