3.3 Charging the Battery
Your phone is powered by a rechargeable battery. The new battery is partially charged. A sound alert will
warn you when the battery level becomes low.
Make sure the battery is not removed. To charge the battery, plug in the connector at the left side of your
phone (USB interface) and then plug the other end into an AC power socket.
Note: the nominal voltage of battery is 3.7 VDC; the charge restriction voltage is 4.2 VDC.
The battery symbol indicates the charging status.
During charging, the charge indicators will scroll; it takes about 3 hours to fully charge the battery.
When all the scroll bars are steady, the battery is fully charged. You can then disconnect the charger.
