Using Your Speakerphone

On the speakerphone-equipped models (8124S-**, 8112S-**, and

8212S-**) 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).

Your speakerphone's sound-activated switches allow either the

microphone or the loudspeaker to be on at a given time. This means that

sounds travel in only one direction at a particular moment.
