About the indicators
CHARGE indicator (orange)
| Turns off | Charging the speaker is completed. |
| Lights up (orange) | The speaker is being charged. |
| Flashes slowly (orange) | The built-in battery is running low and needs to be charged. In this state, the speaker cannot supply power to other devices. |
| Flashes three times (orange) and turns off | If the CHARGE indicator flashes three times in orange and goes off when you turn on the speaker, the battery is empty and needs to be charged. |
Note
- 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. In these conditions, the CHARGE indicator keeps flashing in orange quickly, but this is not a malfunction. To resolve these issues, unplug the AC adaptor and plug it in again within the operating temperature of between 5 °C and 35 °C (41 °F and 95 °F).
