11 Phone security
Note: The phone must be switched on to use these functions.
Do not switch on the phone when the use of a wireless phone is
prohibited or when it may cause interference or danger.
You can lock your keypad, restrict selected calls, and use security codes to
secure your phone against accidental or unauthorized use.
• LOCK AND UNLOCK THE KEYPAD (KEYGUARD)
Remember to lock the phone keypad to prevent accidental calls. If the
keypad is locked, it unlocks when you receive a call. After the call the lock
automatically reactivates.
Note: When Keyguard is on, calls may be possible to dial emergency
numbers (for example, 911 or other official emergency numbers).
Key in the emergency number and press the Talk key. The number
is displayed only after you have keyed in its last digit.
