The time stated above may vary depending on the ambient temperature or conditions of use.
When the battery is running low
When the CHG (charge) indicator flashes slowly in orange, the battery is running low and needs to be charged.
Recommended system environment of computer for USB charging
Windows® 10, Windows® 8.1, Windows® 8, Windows® 7 SP1, Mac OS X (version 10.6 - 10.12)
Operation in all computers with the above environment is not guaranteed.
Operation in a home-built computer is not covered by the warranty.
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). In this case, it
may take longer to charge the battery than compared to 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
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 a booted computer/AC outlet and battery by connecting/disconnecting the USB cable, the speaker
may stop sound output for a short while. This is not a malfunction.
When using the speaker for the first time, be sure to charge the battery for more than 1 hour before turning on the power.
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 CHG (charge) indicator keeps flashing in orange quickly, but this is not a malfunction. To resolve these issues, disconnect the
micro-USB cable 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.
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.

If the CHG (charge) indicator stays turned off when the speaker power is off and connected to a USB device, the built-in
lithium ion battery is fully charged. Once the battery is fully charged, it will not be charged further even if the speaker is kept
connected to a USB device.
