Speakerphone
Characteristics
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 enhanced.
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).
Speakerphone User Guidelines
· 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.
· 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, con-
stant sound patterns—such as elongating your words and playing exter-
nally-supplied music—may prevent the sound-activated switches from
operating properly.
