The phone can be used while the battery is charging, but
this will cause the phone to charge more slowly.
Note:
You must fully charge the battery before using your phone for the first
time. A discharged battery is fully recharged in approximately 160 minutes.
1. With the battery in position on the phone, connect the
lead from the travel adapter to the bottom of the phone.
2. Connect the adapter to a standard AC wall outlet.
3. When charging is finished, disconnect the adapter from
the power outlet and from the phone by pressing the
gray tabs on both sides of the connector and pulling out
the connector.
