Built-in battery life (after the built-in battery is charged for 10 minutes)
10 minutes of charging provide approximately 70 minutes of music playback. (Provided that the volume level is set to 34
and the STAMINA power option is activated.)
The built-in battery life above is measured using our specified music source.
Actual performance time may vary from the listed time due to the volume, songs played, surrounding temperature, and
usage conditions.
When the built-in battery is running low
When you hear voice guidance (Low Battery, Please Recharge Speaker) and the CHARGE indicator starts flashing
slowly, the built-in battery is running low and needs to be charged.
When the remaining battery decreases to such a level that the speaker cannot be turned on, you hear voice guidance
(Please Recharge Speaker. Power Off.) and the speaker automatically turns off. In such a case, charge the speaker.
If the CHARGE indicator flashes 3 times in orange

While the speaker is in Battery Care mode, the CHARGE indicator flashes 3 times in white and goes out.
Hint
You can charge the speaker's built-in battery by connecting the USB cable connected with the speaker to a computer that comes
equipped with a USB charging port as well. However, not all the computers are tested and found compatible with this procedure
and the procedure is not applicable to home-built computers.
As long as the speaker is connected to an AC outlet by a USB AC adaptor (commercially available) or to a computer that comes
equipped with a USB charging port, the speaker's built-in battery is capable of charging itself even while music playback from the
speaker is in progress. However, it may take a long time before charging completes depending on the usage of the speaker. It is
recommended that you turn off the speaker before battery charging.
Note
Depending on the type or specifications of the USB 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 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.
The maximum power output will be lower when the built-in battery is running low.
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. To resolve these issues, disconnect the USB cable, and then connect it again within an operating temperature
between 5 °C and 35 °C (41 °F and 95 °F).
Do not charge the speaker's built-in battery in places where water may splash on it. The supplied USB Type-C cable as well as
the USB port behind the cap are designed neither for waterproof nor for dustproof.
Even if you do not intend to use the speaker for a long time, charge the built-in battery sufficiently once every 6 months to
maintain its performance.
When the Android smartphone is configured to use only A2DP (Advanced Audio Distribution Profile) for establishing
BLUETOOTH connections, the remaining battery power of the speaker is not displayed on the smartphone.
