Locking and Unlocking
Your phone offers two lock functions: locking the display, or
locking the phone. Because this is a touch screen phone, the
display prevents unintentional key presses and can minimize
unnecessary battery drainage. Locking the phone can prevent
unauthorized access to the information on your phone, while
allowing access to the Keypad for call functions.
