(170-1112)                 Security

LOCKING YOUR PHONE

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

When the phone is locked, Loc'd appears when you press any key (except
[PWR]).  When the phone is locked and receives a call, it rings 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
       six-digit security code to display the lock code.  See "Displaying
       the Lock Code" below.
