13 Phone security
Your phone is equipped with different security features that allow you to do 
the following:
• Avoid making accidental calls
• Prevent unauthorized use of your phone
• Restrict outgoing or incoming calls
 • LOCK THE KEYPAD (KEYGUARD)
The keyguard disables your keypad to prevent accidental 
key presses (for example, when your phone is in your 
pocket or purse).
• To lock the keys, select Menu and press the

 key.
• To unlock the keys, select Unlock
 and press the

 key.
Note: When the keyguard is enabled, the 
keypad and display cannot light if you press a 
key. Press the Power key briefly to activate the 
keypad and display lights.
Automatic keyguard
You can have your phone automatically lock the keys after a time you specify.
