Phone
You can lock your phone manually or set the phone to lock 
automatically whenever you turn it off.
To use a locked phone, you must enter the unlock code. A 
locked phone still rings or vibrates for incoming calls or 
messages, 
but you must unlock it to answer
.
You can make emergency calls on your phone even when 
it is locked. For more information, see page 39.
