NOTE
•
Remove the AC adapter from the outlet after the device is fully charged. This
prevents unnecessary power consumption.
•
Another way to charge the battery is by connecting a USB cable between
the device and a desktop or laptop computer. This may take a longer time
than charging the battery in the common way.
•
Do not charge the battery by using a USB hub that is unable to maintain the
rated voltage. Charging may fail or unintentionally stop.
