What the Features Do
Here are brief descriptions of 31 features, including what each one does and how
you might want to use it. The first 24 are voice features and the final 7 are
display features.
Note: You will automatically have the following features on your voice terminal:
Conference, Drop, Hold, Message, Mute, the Select Button, Select Ring, Self-Test,
and Transfer voice features and Normal mode among the display features. You may
also be able to use the Speakerphone (and Reset Speakerphone) or the Speaker
feature. Check with your System Manager to see what other features you can use
with the DEFINITY Generic 1 or the System 75 switch.
Voice Features
Abbreviated Dialing (AD) Allows you to store selected phone numbers for quicker
and easier dialing. Each number can be a complete or partial phone number, an
extension number, or a trunk or feature code. There are 4 possible types of lists—
personal, group, system, and enhanced—and you can have a total of 3 out of 4 lists.
Numbers on a personal list are programmable by you; numbers on all other lists are
programmable only by the System Manager. Use as a timesaver for dialing frequently
called, lengthy, or emergency numbers.
Automatic Callback Sends you a special 3-burst ring tone indicating that a
previously busy or unanswered extension is now available. Use to avoid constant
redialing when you wish to speak to someone as soon as possible.
Note: Can be used only for extensions, not outside numbers.
Bridging Permits you to answer or join in calls to someone else’s extension by
pressing a bridged appearance button on your voice terminal. This button can be any
call appearance button labeled with another user’s primary extension number, as
assigned to you by your System Manager. Use to assist in handling calls for a
designated co-worker.
Call Coverage Provides automatic redirection of certain calls to your voice terminal
for answering. (Your System Manager determines which calls will be sent to you.)
Use to answer calls for other extensions for whom you provide coverage.
Call Forwarding All Calls Temporarily forwards all your calls to another extension
or to an outside number. Use when you will be away from your voice terminal and
you want your calls to be forwarded to a phone number of your choice.
Call Park Puts a call on hold at your voice terminal for retrieval at any extension.
Use when you need to go elsewhere to get information during a call, or whenever you
wish to complete a call from a different location. Also, if the call received is for
someone else, use it to hold the call until the called party can answer it from the
nearest available voice terminal.
4

Call Pickup Lets you answer a call at your voice terminal for another extension in
your pickup group. Use when you wish to handle a call for a group member who is
absent or otherwise unable to answer. Note: You can only use this feature if you and
the called party have been assigned to the same pickup group by your System
Manager.
Conference Allows you to add parties to a call, so that you can conduct up to a
6-way conversation. (If you wish to conference more than 6 parties, call your
attendant for assistance.) Use to set up time-saving conferences, or to spontaneously
include a party important to a discussion.
Drop Disconnects from a call without requiring you to hang up the handset or press
the switchhook. Can also be used with the Conference feature to disconnect the last
party added. Use whenever you are using the handset and want to continue using it
for another action after ending a call.
Hold Temporarily disconnects from a call, holding it until you can return to it.
While a call is on hold, you can place another call, activate another feature, answer a
waiting call, or leave your voice terminal to perfom another task. Use when you
have a call that you don’t wish to drop, but which you have to interrupt briefly to do
something else.
Intercom Gives you quick access to specified extensions. With Automatic
Intercom, you can call a predetermined partner by pressing a single feature button.
With Dial Intercom, you can call any member of a predetermined group of users by
pressing a feature button and then dialing the group member’s 2- or 3-digit code.
Use to rapidly dial frequently called numbers.
Last Number Dialed Automatically redials the last number you dialed, either an
extension or an outside number. Use to save time in redialing a busy or unanswered
number.
Leave Word Calling Leaves a message for another extension to call you back. The
called party will be able to dial message service (for example, attendant, AUDIX,
covering user, etc.) to retrieve a short, standard message which gives your name and
extension, the date and time you called, and the number of times you called. Use
any time you wish to have someone call you back; it will help cut down on repeated
call attempts.
Message Your Message light goes on to let you know that a caller has left a
message for you. You can then retrieve your message by using the Voice Message
Retrieval feature described in the Voice Features section or the Message Retrieval
feature described in Display Features.
Mute Turns off the microphone of the built-in speakerphone or the handset. Use
when you want to confer with someone in the room with you, but you do not want
the other party on the call to hear your conversation.
Priority Calling Allows you to call an extension with a distinctive 3-burst ring to
indicate that your call requires immediate attention. Use when you have important
or timely information for someone.
5

Reset Speakerphone Initiates an acoustic test of the surrounding environment by
using a series of tones. When the tones stop, your speakerphone has finished
adjusting itself for optimal performance. It is now ready for use. Use whenever you
move your voice terminal to a different location (even in the same room), or
whenever the light next to [ Speaker Reset Spkr ] is fluttering. (For best results, use the Reset
Speakerphone feature when the handset is on-hook.)
Select Ring Allows you to select your own personalized ring from among 8 available
patterns. Use to distinguish your ring from that of other nearby voice terminals.
Self-Test Activates the lights and ringer on your voice terminal. Use when you
want to check to see if the ringer, display, and lights on your voice terminal are
working properly.
Send All Calls Temporarily sends all your calls to the extension of a person
designated to answer them when you cannot (perhaps a secretary or receptionist).
Use when you will be away from your desk for awhile, or when you do not wish
to be interrupted by phone calls.
Speaker Allows you to place calls or access other voice features without lifting the
handset. However, in order to speak to the other party, you must use the handset
(the speaker must be off). Use with feature activities that require listening only, such
as on-hook dialing, monitoring calls on hold, and group listening situations.
Note: Your voice terminal has either the Speaker (listen-only) or the Speakerphone
function. Check with the System Manager to see how your voice terminal is set.
Speakerphone Allows you to place and answer calls or access other voice features
without lifting the handset. When used with [ Select ], the built-in speakerphone
performs a test of the surrounding acoustic environment and adjusts itself for optimal
performance. (See Reset Speakerphone.) Use the built-in speakerphone any time you
prefer hands-free communication, both speaking and listening, or for group conference
situations. Note: Your voice terminal may be set for the Speaker (listen-only) rather
than the Speakerphone (listen and speak) feature. Check with your System Manager.
Transfer Transfers a call from your voice terminal to another extension or outside
number. Use when your caller needs to speak further with someone else.
Note: Calls from an outside number to your voice terminal can be transferred only to
an extension, not to another outside number.
Voice Message Retrieval Gives you messages (via computerized voice) left for you
through Leave Word Calling or as typed by a covering user. If authorized by your
System Manager, you may also retrieve messages for one or more of your co-workers.
Use to hear all messages received while you were away.
6

Display Features
Inspect Shows you call-related information for an incoming call when you are
already active on a call. Use to identify and screen new calls.
Integrated Directory Searches for the extension of another user by allowing you to
key in the user’s name with the dial pad. Use as a handy quick reference source for
extension number information.
Message Retrieval Allows you to retrieve messages left for you that have turned on
your Message light. Will also let you retrieve messages for other voice terminals not
equipped with a display (if you are authorized as a systemwide message retriever by
your System Manager). Use to quickly and conveniently check messages, even when
you are already on a call.
Normal Identifies current call appearance, calling/called party, and calling/called
number. Use to see who is calling you and, when placing a call, to verify the number
you have dialed.
Stored Number Allows you to check the number stored on an Abbreviated Dialing
button or as an item on an Abbreviated Dialing list. Also lets you see what number
you last dialed (via Last Number Dialed feature). Use to verify Abbreviated Dialing
list items before placing a call or reprogramming a number, and to make sure that
Last Number Dialed is appropriate to use.
Time/Date Shows you the date and time. Use as a handy calendar and clock.
Timer Allows you to measure elapsed time. Use as an easy and convenient way of
keeping track of time spent on a call or task.

How to Use the Features
The procedures which follow give short, step-by-step instructions for using each of the
voice features and display features. For your convenience, features in both categories
are listed alphabetically.
Special Instructions
The first time you use these procedures, you will need to customize them for yourself
by following the directions below. Your System Manager can supply the information
required.
To the right of each feature name is a box. For each feature that you have,●mark a [ ✔] in the blank box as a reminder. (Voice features Conference,
Drop, Hold, Message, Mute, Select Ring, Self-Test, and Transfer and display
feature Normal mode are already marked for you.) Ask your System Manager if
your voice terminal is set for the Speaker (listen only) or the Speakerphone
(speak and listen) feature, and then place a check in the box beside that feature
also.
Note: If your voice terminal is set for the Speakerphone feature, you can put a
check in the box beside the Reset Speakerphone feature.
Most of the voice features can be activated or canceled by dialing 2- or 3-digit
codes (if they are not already assigned to a button). In the blanks provided
within the procedures, write in the feature code numbers.
●
general rules.
As you operate the features on your voice terminal, keep in mind the following
●Follow carefully all the steps listed in the procedure for the particular feature
you are using.
●If you receive an intercept tone (high-pitched, alternating high and low tone)
while attempting to operate any feature, you have taken too much time to
complete a procedural step or have made a dialing error. Hang up, get a dial
tone, and begin again at Step 1.
●System 75 is available in more than one version. Some features, such as
Abbreviated Dialing, Call Forwarding All Calls, Last Number Dialed, and
Priority Calling operate slightly differently with Version 1, and possibly
Version 2, than they do with later versions. If you are using Version 1 or 2 of
the System 75 software, you should check the section titled Troubleshooting
later in this guide before you use you use any of these 4 features.
