Note
The speaker that is in use can be charged if it is connected to an AC outlet via the supplied AC adaptor. In this case, it may take
longer to charge the built-in battery depending on the conditions of use. Therefore, it is recommended to turn off the speaker
when charging.
When you use the speaker at a loud volume for a long time, the built-in battery may run low even if the speaker is connected to
an AC outlet. As a result, sound becomes low. This is not a malfunction. Turn off the speaker and charge the built-in battery
sufficiently.
In an extremely cold or hot environment, charging stops for safety. If charging takes a long time, it also makes charging of the
speaker stop. To resolve these issues, disconnect the supplied AC adaptor or a USB AC adaptor (commercially available) from
the speaker and connect it within an operating temperature between 5 ℃ and 35 ℃ (41 °F and 95 °F). Then, charge the built-in
battery again.
