GCA70-313 Speakerphone Characteristics

C 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 operat- ing properly. Avoid placing the speakerphone where it will detect sounds from typewriters, keyboards, printers, paging systems, and other equip- ment.

￿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 externally-supplied music—may prevent the sound-activated switches from operating properly.
