Checking the charging completion
If the built-in battery is fully charged when you connect the speaker to an AC outlet with a USB AC adaptor (commercially
available), the CHARGE indicator lights up in orange then turns off after about 1 minute.
When using the Android™ smartphone with Android 8.1 or later installed
When the speaker is connected with the Android smartphone via an HFP (Hands-free Profile) BLUETOOTH
connection, tap [Settings] - [Device connection] - [Bluetooth] on the smartphone. The remaining battery power of the
speaker is displayed along with the connected BLUETOOTH device name. For details, refer to the operating
instructions supplied with the Android smartphone.
Note that the remaining battery power displayed on the smartphone may vary from the actual remaining battery
power of the speaker. Consider this information as a reference.
When using the iPhone

remaining battery power of the speaker is displayed on the widget screen of the iPhone. For details, refer to the
operating instructions supplied with the iPhone.

usage conditions.
When the built-in battery is running low
When the CHARGE indicator starts flashing slowly, the built-in battery is running low and needs to be charged.
If the CHARGE indicator flashes 3 times in orange and goes out when you turn on the speaker, the built-in battery is
empty and needs to be charged.
Hint
You can charge the speaker's built-in battery by connecting 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.
Turn on STAMINA on "Sony | Music Center" to reduce the power consumed while using the rechargeable built-in battery so you
can enjoy playing music for a longer time.
