1.3 Charging the Battery
New batteries are shipped partially charged. Before you start using your
device, it is recommended that you install and charge the battery. Some
batteries perform best after several full charge/discharge cycles.
Note: Only the AC adapter and USB sync cable provided with your
device must be used to charge the device.
Connect the USB connector of the AC adapter to the sync connector on
your device, and then plug in the AC adapter to an electrical outlet to
start charging the battery.
As the battery is being charged while the device is on, a charging icon
appears in the title bar of the Home screen. After the battery has been
fully charged, a full battery icon appears in the title bar of the Home
screen.
Warning: • Do not remove the battery from the device while you are
charging it using the AC or car adapter.
• As a safety precaution, the battery stops charging before it overheats.
