1 Connect the USB Adapter and USB cable (as
shown on the previous page).
2 Plug the USB cable (as shown on the next image)
into the phone's Charger/Accessory Port. Make
sure the 'B' side on the USB cable is facing
upwards.
NOTE
The battery must be fully charged initially to improve
battery lifetime.
NOTE
Your phone has an internal antenna (as shown on the
next page). Be careful not to scratch or damage this
rear area, as that will cause loss of performance.
When charging your phone with a fully discharged
battery, the keypad LED will briefly flash indicating
charging is occurring in a mode designed to prevent
battery damage. The blinking will stop and normal
charging will commence once a sufficient minimum
charge has been established.
