A Quick Look at the Features
Here are brief descriptions of some features, including what each one does and how
you might want to use it. The first features are voice features followed by display
features. You will have the Conference, Drop, Hold, Message, Mute, Select Ring, Self-
Test, Shift, and Transfer voice features, and Message Retrieval and Normal display
features. In addition, you may have many of the other features listed here; your
System Manager can advise you.
Voice Features
Abbreviated Dialing (AD) Allows you to store selected telephone numbers as 3 or
fewer digits for quick and easy dialing. Each number can be a complete or partial
telephone number, an extension number, or a trunk or feature code. There are 3
possible types of lists — personal, group, and system — and you can have a total of 3
lists. Numbers on a personal list are programmable by you; numbers on all other lists
are programmable only by the System Manager. Use this feature as a timesaver for
dialing frequently called, lengthy, or emergency numbers. Note: Check with your
System Manager for the types of lists you have and how many of each.
Automatic Callback Sends you a special 3-burst ring tone indicating that a
previously busy extension is now available. Use to avoid constant redialing when you
want to speak to someone who is frequently busy on the telephone. Note: You can
use this feature only for extensions, not outside numbers.
