Go to the mailbox you need to have in the directory and in the main menu press options (3), then press 9 (this option is not voiced) that will activate the original tutorial. Close the box and then go back in, listen to the tutorial and skip your way through to where it asks you to enter the first 3 letters of the last name, do that then close the box. Go back in again and press * (star) to delete the tutorial when it begins.
