Lock code
The default lock code for your phone is generally the last four digits of your
phone number. You can enter a personal lock code and later change the lock
code as often as you like.
To enter a new lock code:
1. Press for Security. Enter your current lock code.
2. Press for Change Lock . The screen prompts Lock code. Enter a
new, 4-digit lock code by pressing the keypad. You will be prompted to
Re-Enter. Enter the same 4-digit lock code.
3. Press to save the new lock code, or press to exit.
Note: Your phone does not allow viewing of the lock code unless you know
the lock code (this is for obvious security reasons). So, if you change the
lock code, be sure to write down or memorize the new code.
