Unable to charge the battery.
Turn off the headphones and charge the battery again.
Check that the headphones and your computer are firmly connected using the micro-USB cable (supplied).
Check that the computer is turned on and not in standby, sleep, or hibernation mode.
Check that the headphones and the computer are directly connected, and not via a USB hub.
Try the USB connection procedure again in cases other than those stated above.
The USB port of the connected computer may have a problem. Connect the headphones to another USB port of the
computer if available.
A USB AC adaptor that is not recommended is being used.
The battery is fully charged.
If the battery is fully charged, the POWER indicator may blink in red and go off, and charging may not start. This is
not a malfunction.
If the headphones had not been used for a long time, it may take a while to light up the POWER indicator in red
when the headphones are connected to your computer or an AC outlet to charge the battery. In this case, do not
disconnect the micro-USB cable from the headphones, and wait until the POWER indicator lights up in red.
When Windows 8.1 is used for your computer, update your system to the latest version via Windows update.
