The following figure shows a phone with two Line Keys (1951 and 1952), and
four Speed Dial Keys (assigned to Lauren Gates, Jack Jones, Milton Stone, and
Teresa Swift).
When a new entry is added to the Contact Directory, it is automatically
assigned a speed dial index number, as well as the next available position
under the Line Key(s). The phone populates all available positions with the
contacts that have the lowest speed dial index numbers.
Speed Dial Keys display consecutively according to the speed dial index
number (the lowest speed dial index number displays first). To re-order Speed
Dial Keys, see Updating Speed Dial Keys on page 3-40 .
For information on assigning or updating speed dial index numbers, see
Updating Contacts in Your Local Contact Directory on page 2-58 . For
information on placing calls using speed dials, see Placing Calls Using Speed
Dial on page 3-10 .
