1.3 Charging the Battery via the USB Cable
When charging the battery for the very first time, you should charge it for at least
8 hours.
1. Turn on the computer.
2. Connect the mini-USB end of the USB cable to the bottom of your device and
the other end to a USB port on your computer.
The charge indicator glows amber when charging is in progress. Do not
disconnect your device until the battery is fully charged, when the charge
indicator turns green. This will take a couple of hours.
CAUTION: For optimal performance of the lithium battery, take note of the following:
Do not charge the battery where the temperature is high (e.g. in direct sunlight).
There is no need to fully discharge the battery before charging. You can charge the battery
before it is discharged.
If you will not use the product for a long period of time, be sure to fully charge the
battery at least once every two weeks. Over discharge of the battery can affect the
charging performance.
