1.7 Speakerphone Usage Guidelines
When using your EP100, 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 strength-
ened.
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).
• 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 EP100 where it will
detect sounds from keyboards, printers, paging systems,
typewriters, 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, constant sound patterns—such as elongating your
words and playing externally-supplied music—may prevent the
sound-activated switches from operating properly.
