Checking the battery level of the rechargeable battery
After pressing or holding the (call) button for more than 3 seconds to check the battery power during the speaker is turned
on, the voice guidance “Fully charged/About 70%/About 50%/About 20%/Please charge” outputs from the speaker.
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.
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 a booted computer or AC outlet via a USB AC adaptor (not supplied) 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 to 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 a booted computer. 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 a booted computer. As a
