About the indicators
CHARGE indicator (orange)
| Turns off | Charging the speaker is completed. |
| Lights up | The speaker is being charged. |
| 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. |
| Flashes 3 times and turns off | If the CHARGE indicator flashes 3 times and goes off when you turn on the speaker, the battery is empty and needs to be charged. |
Note
- A speaker that is in use can be charged if it is connected to an AC outlet though the CHARGE indicator does not light up. In this case, it may take longer to charge the 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 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 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 AC adaptor from the speaker and connect it again within the operating temperature between 5 °C and 35 °C (41 °F and 95 °F).
