Charging the speaker
The speaker can be operated by connecting it to an AC outlet via the USB AC adaptor (commercially available) or by
using the built-in 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
power.
You can operate the speaker with the built-in battery by charging the speaker before use.
Checking the charging completion

USB AC adaptor (commercially available). After that, plug the USB AC adaptor into an AC outlet.
The speaker supports a USB AC adaptor (commercially available) with an output current of 500 mA or more.
However, using a USB AC adaptor with an output current of 1.5 A or more and a supplied micro-USB cable or
micro-USB cable conforming to the USB standard is recommended. Charging from the other device is not
