Lock the keypad (Keyguard)
Remember to lock your phone’s keypad to prevent accidental calls. If the
keypad is locked, it unlocks when you receive a call. After the call, the lock
automatically reactivates.
Important:
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 appears in the display after you’ve keyed in the last digit.
To lock the keypad, press

SECURITY LEVELS
The security level determines your access to features when a non-owner
SIM card is used. A non-owner SIM card is one (other than the original) that
is inserted after you power off the phone. There are three security levels:
Off
–Owner and non-owner cards are treated the same.
Memory
–Non-owner cards can access SIM memory. Any changes to
the memory setting requires the security code. The owner card has
access to all features, but the security code is required to change a
memory setting.
Phone
–The security code is required upon power-up.
