k Phone Lock Setting
This setting specifies whether the phone should be locked
whenever it is turned on.
Lock Mode prevents the unauthorized use of your phone. Once
the phone is locked, it is in restricted mode until the Lock Code is
entered. You can receive phone calls and still make emergency
calls. You can modify the Lock Code using the new Lock Code
within the Security menu.
