Power source/charging

Charging the speaker

The speaker is capable of running on power either from an AC outlet connected by the AC adaptor (supplied) 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.

1. Connect the speaker to an AC outlet to charge it.

Connect the supplied AC adaptor to the DC IN 5V port on the speaker and an AC outlet.

Battery charging starts and the CHARGE indicator lights up in orange. Charging will complete in about 5 hours* and the indicator will turn off.

*Time that is required to charge the empty built-in battery to its full capacity when the speaker turns off.

After you disconnect the AC adaptor 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 waterproof and dust proof 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 BATT (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.

80% or more: “Battery fully charged”

60% or more: “Battery about 70%”

40% or more: “Battery about 50%”

20% or more: “Battery about 30%”

Less than 20%: “Please charge”

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.
• When using the Android smartphone with OS 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/iPod touch with iOS 10.0 or later installed. While the speaker is connected with the iPhone/iPod touch via an HFP (Hands-free Profile) BLUETOOTH connection, the remaining battery power of the speaker is displayed on the widget screen of the iPhone/iPod touch. For details, refer to the operating instructions supplied with the iPhone/iPod touch.

Note that the remaining battery power displayed on the iPhone/iPod touch may vary from the actual remaining battery power of the speaker. Consider this information as a reference.

When the built-in battery is running low

When the voice guidance says “Please charge” and the CHARGE indicator flashes slowly, the built-in battery is running low and needs to be charged. In this state, the speaker cannot supply power to other devices.

Using a commercially available USB AC adaptor for battery charging

The speaker supports USB AC adaptors that are capable of delivering an output current of 3.0 A or 1.5 A.

(Using a USB AC adaptor capable of delivering an output current of 3.0 A for battery charging reduces the charging time.)

Be sure to use a USB Type-C® cable (compliant with the USB standard) that supports the output current of your USB AC adaptor.

Power supply

Unable to charge the speaker

• Make sure that the AC adaptor is connected securely to the speaker. Then, make sure that the AC adaptor is connected securely to an AC outlet.
• The speaker supports USB AC adaptors that are capable of delivering an output current of 3.0 A or 1.5 A. (Using a USB AC adaptor capable of delivering an output current of 3.0 A for battery charging reduces the charging time.) Be sure to use a USB Type-C® cable (compliant with the USB standard) that supports the output current of your USB AC adaptor. Use of a USB AC adaptor with an output current of less than 1.5 A is not guaranteed for battery charging. The charging time may vary depending on the ambient temperature or the usage of the speaker as well.
• Depending on the type or specifications of a commercially available 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.

Unable to turn on the speaker or the speaker suddenly turns off

• The rechargeable built-in battery may be empty or running low. Connect the speaker to an AC outlet with the supplied AC adaptor for battery charging.
• Depending on the type or specifications of a commercially available 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 auto power off (Auto Standby) function may have activated. After about 15 minutes in certain circumstances, such as when the volume of the audio input is low, the power will automatically turn off. Raise the volume of the connected device for use, or set the auto power function to off.

Sound

No sound/Sound from only one speaker/Low sound level/Distorted sound/Humming or noise in the speaker output/No voice or low voice from callers

• Check that both the speaker and the connected device are turned on.
• Turn up the volume of the speaker and the connected device.
• Check that the connected device is playing.
• Make sure the audio cable is disconnected from the AUDIO IN jack during playback in BLUETOOTH mode.
• Make sure the audio cable is firmly connected to the AUDIO IN jack during playback in AUDIO IN mode.
• If you are connecting a computer to the speaker, make sure the audio output setting of the computer is set for a BLUETOOTH device.
• Check that the speaker has established BLUETOOTH connection with the BLUETOOTH device.
• Pair the speaker and the BLUETOOTH device again.
• If the device that is connected to the AUDIO IN jack is monaural, sound may only be output from the left speaker component (left channel).
• If the connected device has an equalizer function, set it to off.
• Keep the speaker away from a microwave oven, Wi-Fi®, etc.
• Bring the BLUETOOTH device closer to the speaker. If there is any obstacle between the speaker and the BLUETOOTH device, move it out of the way.
• If the CHARGE indicator flashes slowly, turn off the speaker and charge the built-in battery sufficiently.
• A device with a built-in radio or tuner cannot be connected to the speaker via BLUETOOTH since noise may occur in broadcasts.
• Locate the speaker farther away from a TV, radio or tuner, etc. since noise may occur in broadcasts.
• When using the Stereo Pair function or Party Connect function, if any other BLUETOOTH device(s) such as a BLUETOOTH mouse or BLUETOOTH keyboard is connected to the BLUETOOTH device, terminate the connection between them.
• There are some BLUETOOTH devices that can have the wireless playback quality changed. If your device is compatible with this function, select “Priority on stable connection (SBC)” over sound quality. For details, refer to the operating instructions supplied with the device.
• Select “Priority on stable connection (SBC)” for the wireless playback quality of the speaker.
• Install the latest version of “Sony | Music Center” on the connected device. If you cannot use the latest version of “Sony | Music Center” or you cannot connect the speaker and a BLUETOOTH device via BLUETOOTH connection, uninstall “Sony | Music Center” and install it again.
• When receiving/making a phone call, check that output of the BLUETOOTH device is set for the speaker.

Sound becomes low while in use

• The sound may become low in the following cases. This is not a malfunction.
  • When the built-in battery is running low and the CHARGE indicator flashes slowly, while the speaker is being powered by the built-in battery only.
  • When the rechargeable built-in battery is running low as a result of long-time use of the speaker at a loud volume even though the speaker was connected to an AC outlet by the AC adaptor (supplied).
