3. The charge indicator glows in amber when charging is in progress. Do not
disconnect your device from AC power until the battery is fully charged, as
indicated by the amber indicator turning into green. This will take a couple of
hours.
CAUTION: For optimal performance of the lithium battery, take note of the
following:
Use the included AC adapter only.
There is no need to fully discharge the battery before charging. You can
charge the battery before it is discharged.
Do not charge the battery where the temperature is high (e.g. in direct
sunlight).
As a protection against damage, your device stops charging when the battery’s
temperature is extremely high or low. In high temperature conditions, the
charging stops when the battery’s temperature gets above 70C (158F) and
continues when the temperature lowers to 60C (140F). In low temperature
conditions, the charging stops when the temperature gets below -5C (23F)
and continues when the temperature rises to 0C (32F).
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.
