							1.2 Using 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 8412F-** 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 8412F-**.
The 8412S-**, however, can only function in half-duplex
mode. Only the guidelines in section 1.2.2 are applicable to the
8412S-**.
1.2.1 Full-Duplex Speakerphone Guidelines
TheImpact SCS8412F-** speakerphone uses the latest full-duplex
speakerphone technology. (Full-duplex technology enables both parties
on a speakerphone call to speak simultaneously—half-duplex
speakerphones carry only one person’s voice at a time.) The 8412F-**
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.
To operate in full-duplex mode, the telephone must perform a “speech
training” test at the beginning of each call. 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 8412F-** 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 8412F-** from
operating in full-duplex mode.
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.

							Depending on telephone line conditions and the type of speakerphone the
distant party is using, it may not be possible for the 8412F speakerphone
to operate in full-duplex mode. If the distant party’s speakerphone is a
half-duplex model and both you and the distant party are in
speakerphone mode, the half-duplex speakerphone controls the
communications mode and prevents the 8412F from operating in
full-duplex mode.
To maximize the usefullness of your full-duplex speakerphone, take note
of these following observations about full-duplex speakerphone
operation.
•The full duplex operating mode requires a small amount of time to
adapt to changes in echo; therefore, you should avoid making any
movements in the vicinity—about a one-foot radius—of the
speakerphone.
•There are certain echo limits beyond which the speakerphone cannot
effect canceling. These limits are as follows: room echoes beyond 39
milliseconds (standard configuration) and line echoes beyond 24
milliseconds (standard configuration).
•The speakerphone may automatically reduce the volume in each
direction when both you and the distant party talk at the same time
(double-talk). This volume reduction is necessary to control the
echoes at high volume levels. It is possible for surrounding
conversations and other sounds to trigger double-talk even when you
are not speaking. This condition may lower the loudspeaker volume
at your speakerphone.
•You must adjust the loudness of your voice to match that of the
distant party’s voice. This action is necessary to cause full-duplex
operation to take place. Sustained doulbe-talk or excessive echo may
cause the speakerphone to drop back into half-duplex operation. This
happens because the speakerphone’s echo cancel circuits cannot
adapt during the double-talk situation.
•If both you and the distant party are using full-duplex
speakerphones, the sensitivity to both echo path changes and volume
reduction during double-talk is doubled from the sensitivity when
just one full-duplex speakerphone is involved.
