When the battery is running low
When the voice guidance says "Please charge" and the CHARGE indicator flashes slowly in orange, the battery is running low
and needs to be charged. In this state, the speaker cannot supply power to other devices.
If the voice guidance says "Please charge" and the CHARGE indicator flashes 3 times in orange and goes off when you turn
on the speaker, the battery is empty and needs to be charged.
Hint
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 compared to when the speaker is turned off depending on the conditions of use. Therefore, it is recommended that
you turn off the speaker when charging.
Note
When you use the speaker at a loud volume, the battery may run low even if the speaker is connected to an AC outlet. If you want to use the
speaker while charging, lower the volume of the speaker. Otherwise, turn off the speaker and charge the battery sufficiently.
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.
When you switch the power source between an AC outlet and battery by connecting/disconnecting the AC adaptor, the speaker may stop sound
output for a short while. This is not a malfunction.
The maximum power output will be lower when the battery is running low.
Even if you do not intend to use the speaker for a long time, charge the battery sufficiently once every 6 months to maintain its performance.
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, disconnect the AC
adaptor and connect it again within the operating temperature between 5 °C and 35 °C (41 °F and 95 °F).
Do not charge in places where water may splash.
