• From the main menu, select (General), then (Secure).
• Hold SEC.
1 If you are using a 2221 Handset:
• From the main menu, select (Functions).
• Press or to scroll to the Secure Info function.
•Press (OK).
1 Press or to scroll to the Select Key Index entry.
1 Press or to select the secure key index that you want to use.
