Locking Your Phone

To prevent unauthorized use of your phone, you can enter a 3-digit code to
lock your code at any time (see "Using Manual Lock").  For added
convenience, you can also set the phone to automatically lock every time
you turn it on (see "Using Automatic Lock" below).

When the phone is locked, Locked appears when you press any key (except
[PWR]).  When the phone is locked and receives a call, it rings or vibrates
as usual.  To answer the call, you must enter the lock code and then press
[SND].

Your phone's preset lock code is 123.  For added security, you can change
the code to one that you can easily remember.  See "Changing the Lock
Code" below.

Note:  If you lock your phone then forget the lock code, you can enter a
       6-digit security code to display the lock code.  See "Displaying
       the Lock Code" below.
