Charging the speaker
The speaker is capable of running on power either from an AC outlet connected by the supplied AC power cord (mains lead) or from the rechargeable built-in lithium-ion battery.
When using the speaker for the first time, be sure to charge the built-in battery for more than 1 hour before turning on the speaker.
With the built-in battery charged in advance, you can use the speaker solely with battery power.
Hint
-
For charging the built-in battery of the speaker, the Battery Care mode option is available in addition to the normal charging method. Battery Care mode limits the maximum charge capacity to approximately 90% and makes the battery life last longer. The playback time available in Battery Care mode is shorter than the time available when the built-in battery is charged by the normal charging method. At the time of purchase, the speaker is not in Battery Care mode.
-
While the speaker is turned on, pressing and holding the BATTERY button/
BATTERY CARE button behind the cap on the rear side of the speaker for about 2 seconds places the speaker into Battery Care mode and you hear voice guidance (Battery Care mode, ON) from the speaker. Pressing and holding the BATTERY button/BATTERY CARE button once again for about 2 seconds brings the speaker out of Battery Care mode and you hear voice guidance (Battery Care mode, OFF) from the speaker. -
You can place/bring the speaker into/out of Battery Care mode with “Sony | Music Center” as well.
- Connect the speaker to an AC outlet to charge it.
Connect the AC input jack on the speaker and an AC outlet with the supplied AC power cord (mains lead).
Battery charging starts and the CHARGE indicator lights up in orange. Charging will complete in about 3 hours* and the indicator will turn off.
* Time that is required to charge the empty built-in battery to its full capacity while the speaker is turned off.
After you disconnect the AC power cord (mains lead) from the speaker upon completion of battery charging, be sure to close the cap securely.
The cap plays a very important role in maintenance of the water resistant performance.
Checking the charging completion
If the built-in battery is fully charged when you connect the speaker to an AC outlet, the CHARGE indicator lights up in orange then turns off after about 1 minute.
Checking the built-in battery level of the rechargeable built-in battery
After pressing the BATTERY button behind the cap on the rear side of the speaker, when the speaker is turned on, the voice guidance listed below is output from the speaker depending on the remaining built-in battery power.
81% - 100%: “Battery fully charged”
81% - 90% (Battery Care mode): “Battery Care Mode, Fully Charged, Battery About 90%”
61% - 80%: “Battery about 80%”
41% - 60%: “Battery about 60%”
21% - 40%: “Battery about 40%”
1% - 20%: “Low Battery”
Hint
-
By using “Sony | Music Center,” you can activate/deactivate the voice guidance associated with the remaining battery power that you hear when you turn on the speaker.

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 the voice guidance says “Low Battery” and the CHARGE indicator flashes slowly, the built-in battery is running low and needs to be charged. While in this state, the speaker is not capable of supplying power to other devices and may automatically turn off.
When the remaining battery decreases to such a level that the speaker cannot be turned on, you hear voice guidance (Battery is empty.) and the speaker automatically turns off. In such a case, charge the speaker.
In the event that the CHARGE indicator flashes 3 times in orange and then the speaker turns off when the speaker is turned on, the built-in battery is empty and needs to be charged.
Note
-
When you use the speaker at a loud volume, the built-in 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 built-in battery sufficiently.
-
The maximum power output will be lower when the built-in battery is running low.
-
If the ambient temperature is extremely low or high, the speaker will stop charging the built-in battery for safety reasons. It may also stop charging if charging continues for a long period of time. If such an event occurs, bring the temperature up or down to an operating temperature between 5 °C and 35 °C (41 °F and 95 °F), disconnect and reconnect the supplied AC power cord (mains lead), and then let the speaker charge the built-in battery once again.
-
Do not charge the speaker's built-in battery in places where the speaker is likely to have water splashed on it. The supplied AC power cord (mains lead) as well as the jacks and ports (AC IN/USB/AUDIO IN/OPTICAL IN/MIC/GUITAR) behind the cap are not designed for water resistant.
-
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.
