SRS-XB33

Unable to charge the speaker

When a USB AC adaptor (commercially available) is in use, make sure that the USB cable is connected securely to

the speaker and the USB AC adaptor. Then, make sure that the USB AC adaptor is connected securely to an AC

outlet.

When using a USB AC adaptor (commercially available), make sure that it is capable of delivering an output current

of 1.5 A or more. You can use a USB AC adaptor with an output current of 500 mA or more and less than 1.5 A as

well, but it may take a very long time (10 hours or more) before charging completes. When using such a USB AC

adaptor, it is recommended that you turn off the speaker before battery charging. Use of a USB AC adaptor with an

output current of less than 500 mA is not guaranteed for battery charging.

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

using a USB AC adaptor with an output current of 3.0 A for battery charging, be sure to use a USB Type-C

cable

(compliant with the USB standard) that supports an output current of 3.0 A. The supplied USB cable supports an

output current of up to 1.5 A. Use of any other devices is not guaranteed for battery charging. The charging time may

vary depending on the ambient temperature or the usage of the speaker as well.

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.

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.
