1.2Using Your Speakerphone
When using your speakerphone, the microphone and loudspeaker are
farther away from you than when you use a handset. Both the signal from
the loudspeaker and the signal to the microphone must be strengthened.
When microphones and loudspeakers are close together (such as in a
speakerphone), additional amplification typically generates a ringing
sound (public address systems do this if the volume is too high or the
microphone is too close to a loudspeaker).
NOTE: The 8324F-** speakerphone can function in the full-duplex or
half-duplex mode. Both sets of guidelines (section 1.2.1 and
section 1.2.2) are applicable to the 8324F-**.
The 8012S-**, 8024S-**, 8324S-**, and 8312S-**
speakerphonesonly function in the half-duplex mode—only
section 1.2.2, Speakerphone User Guidelines, apply to these
telephones.
1–2 LCD Speakerphone Reference Manual
GCA70–245Introducing The LCD Speakerphone
1.2.1Using A Full-Duplex Speakerphone
The Impact SCS 8324F-** speakerphone uses the latest full-duplex
speakerphone technology. (Full-duplex technology enables both parties
on a speakerphone call to speak simultaneously—half-duplex
speakerphones allow only one person to speak at a time.) The 8324F-**
will operate in either full-duplex or half-duplex mode depending on the
current line conditions. For example, satellite calls or calls with a delay
involved may prevent the telephone from operating in full-duplex mode.
At the beginning of each call the telephone must perform a “speech
training” test. To achieve optimum performance from the full-duplex
speakerphone, Comdial recommends that each user in turn speak about
10 consecutive words to allow the telephone to “train” itself. Note that
during the “speech training” test, the speakerphone is operating in
half-duplex mode.
Depending on the telephone line conditions and the type of speakerphone
at the other end, it may not be possible for the 8324F-** to operate in
full-duplex mode. If the speakerphone at the other end is a half-duplex
speakerphone and both parties are in speakerphone mode, the half-duplex
speakerphone is the controlling factor, preventing the 8324F-** from
operating in full-duplex mode.
When using a full-duplex telephone, you must be aware of these different
situations and react accordingly when the far-end party does not respond.
However, you will discover it is much easier to interrupt the far-end
talker and have a more natural conversation than you can have with a
half-duplex speakerphone.
NOTE: Pressing any button (mute, hold, etc.) on the speakerphone
while in full-duplex mode causes the system to perform the
“speech training” test again. For example, if you press MUTE
while in full-duplex mode, when you release the call from
mute, the system will perform the entire “speech training” test
again.

1.2.2Speakerphone User Guidelines
NOTE: The speakerphone user guidelines in this section that do not
apply to the Impact SCS model 8324F-** when it is operating
in full-duplex mode are so noted. However, when the 8324F-**
is in half-duplex mode or in “speech training” mode, all of the
following guidelines are applicable.
Both parties can not talk at the same time. You must wait for silence
•
out of your loudspeaker before talking. You must stop talking to hear
the other party. Does not apply to model 8324F-** when in full duplex
mode.
Background noise may prevent the sound-activated switches from
•
operating properly. Avoid placing the speakerphone where it will
detect sounds from typewriters, keyboards, printers, paging systems,
and other equipment.
Speak slightly louder than normal and with a clear, authoritative voice.
•
For the microphone to best detect your voice, speak within three feet
of it and face the telephone.
Raising the volume of the loudspeaker makes it easier for the
•
sound-activated switches in your telephone to select the distant party’s
voice. Lowering the volume of the loudspeaker makes it easier for the
switches to select your voice.
Since the system takes several seconds to provide the best switching,
•
constant sound patterns—such as elongating your words and playing
externally-supplied music—may prevent the sound-activated switches
from operating properly.
Place the telephone on a hard surface and away from table edges. Do
•
not place the telephone in corners or enclosures. Do not let
obstructions come between you and the microphone. Rooms with hard,
flat surfaces that reflect sound may affect the sound-activated switches.
If you are using a handset and the other party is using a speakerphone,
•
avoid breathing heavily into your microphone. Avoid other sounds that
may affect the distant telephone’s sound-activated switches.
In some situations, such as when either you or the distant party are in a
•
noisy environment, you may have to lift your handset to ensure a clear
conversation.
1–4 LCD Speakerphone Reference Manual
GCA70–245Introducing The LCD Speakerphone
When both you and the distant party use speakerphones, the
•
sound-activated switches can occasionally detect both voices
simultaneously, thus blocking out both voices.
•Tomanually place a call using your speakerphone,
1. Press the INTERCOM or line button.
2. Dial the number.
3. When party answers, speak toward the telephone.
•Toautomatically dial a number using your speakerphone,
1. Press the preprogrammed speed dial or DSS button and speak
toward the telephone when your party answers.
•Toanswer a call with your speakerphone,
1. Press the INTERCOM or line button with flashing red

1.7Adusting YourTelephone’s Pedestal
(Models 8312S, 8324S and 8324F only)
An adjustable pedestal is provided on your telephone to allow you to
select the most comfortable viewing angle. When you receive your
telephone, it will be in its lowest position — down flush against the
pedestal. You can raise your telephone to one of three higher positions
as follows:
1. Grasp the rear of the pedestal base firmly with one hand while
lifting the rear portion of the telephone upward with your other
hand.
2. While pivoting the telephone upward with one hand, pivot the
telephone supporting arms upward with your other hand while
feeling for the notches under the telephone. Notice that there
are three sets of notches under the telephone corresponding to
the three positions available.
3. When the telephone is at your desired height, find the closest
pair of notches corresponding to that height, and engage the
supporting arms with the notches. Press down slightly on the
telephone until you feel the supporting arms snap into place.

2.1Using Chapter Two
The main system operator, or attendant, should be familiar with all of
the information contained in this chapter. It is user-friendly and
designed with both the attendant and the station user’s needs in mind. If
you are the system attendant, you should closely study this chapter
before you begin operating the system.
Within this chapter, you will find helpful information on programming
all of the special features on your telephone that are unique to attendant
station operation, and you will also find information on the LCD’s and
their meanings.
NOTE: If possible, read all of this chapter before you attempt to
operate your telephone system.

2.2Creating The LCD Response Messages
When you are busy or are away from your desk, you can set a message
at your telephone that will be received by any LCD speakerphone
within your system. Your system provides two default messages:
“Back at . . .” and “Call . . .” In addition, you can add eight customized
messages, or you can create up to ten messages if you choose not to use
the two default messages.
NOTE: If you intend to create a response message to a voice
announce, remember that this is also a message, and that it
uses one of your message locations.
•Tostore the LCD messages,
1.Write your messages on the chart on page 2-5 (each message can
have up to 16 characters).
2.Use the letter code table (on page 2-4) to assign a number to each
letter.
3.Write these numbers on the chart line beside the message letters.
4.Press INTERCOM.
5.
Dial ✳ #0 5.
6.Dial a message location number (1-0).
7.Dial # to clear current message.
8.Compose your messages by dialing the two-digit codes that relate
to the letters. See the code table on page 2-4.
9.Dial ✳ to save message.
10. Dial next location number, # to clear it, two-digit codes for the
message, and ✳ to save.
11. Repeat previous step until all messages are stored.
12. Press SPEAKER to end.
2–2 LCD Speakerphone Reference Manual
GCA70–245Programming The Attendant Features
Example: Create the message “TAKE MESSAGE” and program it into
message location number 3.
5. When you are finished creating and programming messages, fill
in the list on page 2-5 of this guide. Make a list of the stored
messages and their location numbers, and give each station user a
copy.
The direct inward station dialing (DISD) feature allows an external
party to call an intercom station directly without assistance from the
attendant (over a line programmed for DISD). As the system attendant,
you may instruct callers to make DISD calls when necessary.
You may give the caller a DISD line number and the extension number
associated with the station he or she is trying to reach. Future calls
from the caller to a specific party will not have to be serviced at the
attendant’s station, although a ring-no answer or busy condition at the
called party’s station will result in the system’s handling the call in
another manner (described below).
When a caller makes a DISD call from an outside line, he or she will
initially hear ringing. The system will answer the call with a DISD
continuous dial tone; the caller can then dial an extension number.
If called station is idle, a tone is sounded and called station rings.
•
If the call is answered by another station user, the caller can ask for
•
transfer to desired station.
If ringing stops and dial tone sounds again, the caller can dial another
•
extension number.
If called station has call forward feature set, forward station rings.
•
If called station is busy, call is placed on hold and camped-on at busy
•
station. If camp-on is not answered within a transfer recall timeout
period, busy tone is given, followed by a DISD dial tone.
2–6 LCD Speakerphone Reference Manual
GCA70–245Programming The Attendant Features
NOTE: The system will return the caller to DISD dial tone two
additional times and then drop the line.
If called station is busy but is part of a hunt group, DISD call is
•
routed to idle station in hunt group, if available; otherwise, the call is
camped-on at dialed station. Hunt group is followed when caller hears
ringing but receives no answer.
If an invalid extension number is dialed, an error tone is sounded
•
before DISD dial tone is returned (caller can redial). If mistake indialing is made, caller can dial ✳ for new DISD dial tone.
If extension number dialing is not completed within the programmed
•
dial time limit, call is routed to DISD assist station i f available;
otherwise, the line is dropped.
NOTE: See section 2.14 for DVA programming used with the DISD
feature.

2.4Naming The System Telephones
If you have an LCD speakerphone, this feature lets you know who is
calling you. You can assign either a personal name or a group name to
each system telephone. This name can contain up to seven letters and
will show up in the user’s display and/or in the called party’s display.
Typical names could be SRVC, MKTG 1, K SMITH.
• Name the system telephones as follows:
1. Use letter code table (page 2-9) to compose names for all
telephones requiring them (the system accepts up to seven letters
per name),
2. Press INTERCOM,
3.
Dial ✳
4. Dial the station number of the telephone to be named (10-57),
5.
Dial
6. Dial two-digit codes that correspond to letters in name,
7. Dial ✳ to continue entering station names (repeat above steps
beginning with station selection 10-57),
