Note

  • A speaker that is in use can be charged if it is connected to an AC outlet via a USB AC adaptor (commercially available), or connected to a booted computer. 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 via a USB AC adaptor (commercially available), or connected to a booted computer. 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 micro-USB cable from the speaker and connect it again within an operating temperature between 5 °C and 35 °C (41 °F and 95 °F).
