Your phone is equipped with different security features that allow you to avoid
making accidental calls and prevent unauthorized use of your phone.

The keyguard disables your keypad to prevent accidental key presses.
• To lock the keypad and the power key, close the slide, and press the left
selection key (Lock) to confirm; or select Menu and press * within 3.5seconds.
• To unlock the keypad, open the slide; or select Unlock and press *
within 1.5 seconds.
