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).

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.

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 oper-
ating in half-duplex mode.
