Charging the battery
Use the charger to charge the battery before using it for the first time. A computer can be also used to charge the device by connecting them via the USB cable.
•When the battery power is low, the device emits a warning tone and displays a low battery power message.
•If the battery is completely discharged, the device cannot be turned on immediately when the charger is connected. Allow a depleted battery to charge for a few minutes before turning on the device.
•If you use multiple applications at once, network applications, or applications that need a connection to another device, the battery will drain quickly. To avoid disconnecting from the network or losing power during a data transfer, always use these applications after fully charging the battery.
Charging with the charger
Connect the USB cable to the USB power adaptor and then plug the end of the USB cable into the multipurpose jack.
