Charging the Battery
Fully charge the battery before starting to use the device for the first time.
When charging the battery for the very first time, charge it for at least 8
hours.
1. Plug the converter to the
AC adapter ( ).
2. Connect the DC end of
the AC adapter to the
Mini-USB connector on
the bottom of the device
( ), and plug the other
end of the AC adapter
into a wall outlet ( ).
3. The charge indicator glows in red when charging is in progress. Do not
disconnect the device from AC power until the battery is fully charged,
as indicated by the red indicator turning into green. This will take a
couple of hours.
Whenever possible, keep the device connected to the AC adapter and a
power source. Doing so keeps the battery charged.
NOTE: Your device can also be charged when it is connected to a desktop computer
via the USB cable.
CAUTION: For optimal performance of the lithium battery, take note of the following:
The environment temperature for charging should be 0~40°C.
When a battery is fully discharged due to a long period of usage or idleness,
connect the device to AC power for charging, and wait for at least 5 minutes before
turning it on.
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.
