Hint

A speaker that is in use can be charged if it is connected to a booted computer or AC outlet via a
USB AC adaptor (not supplied). In this case, it may take longer to charge the battery than
compared to 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 a booted computer. If you want to use the speaker while charging, lower the
volume of the speaker. Otherwise, turn off the speaker and charge the battery sufficiently.

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 a booted computer. As a result, sound becomes low. This is not a
malfunction. Turn off the speaker and charge the battery sufficiently.

When you switch the power source between a booted computer/AC outlet and battery by
connecting/disconnecting the USB cable, the speaker may stop sound output for a short while.
This is not a malfunction.

When using the speaker for the first time, be sure to charge the battery for more than 1 hour
before turning on the power.

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. In these conditions, the CHG (charge) indicator keeps
flashing in orange quickly, but this is not a malfunction. To resolve these issues, disconnect the
micro-USB cable and connect it again within the operating temperature between 5 °C and 35 °C
(41 °F and 95 °F).

Do not charge in places where water may splash.

Even if you do not intend to use the speaker for a long time, charge the battery sufficiently once
every 6 months to maintain its performance.
