Charging your device
Your device has an embedded, rechargeable battery that should be replaced only by
Sony or an authorised Sony repair centre. You should never try to open or take apart
the device yourself. Opening the device can cause damage that voids your warranty.
The battery is partly charged when the device is shipped from the factory. Depending
on how long your device was in the box before you purchased it, the battery level
may be quite low. It is therefore recommended that you charge the battery for at least
30 minutes before starting up your device for the first time. You can still use your
device while it is charging. To read more about how to improve the battery
performance, see
Battery and power management on page 27.
