Charging the phone
The charger connector is at the bottom of the phone. Insert one end of the charging 
cable into the phone and plug the other end into an electrical outlet.
NOTE:  The battery must be fully charged initially to improve battery lifetime.
Locking and unlocking the screen
If you do not use the phone for a while, the screen will be automatically turned off and 
locked. This helps to prevent accidental touches and saves battery power.
When you are not using the your phone, press the 
Power/Lock key   to lock your 
phone. 
If there are any programs running when you lock your screen, they may be still running 
in Lock mode. It is recommended that you exit all programs before entering Lock mode 
to avoid unnecessary charges (e.g. phone calls, web access and data communications).
To wake up your phone, press the 
Power/Lock key  . The Lock screen will appear. 
Touch and slide the Lock screen in any direction to unlock your Home screen. The last 
screen you viewed will open.
