Speakerphone User Guidelines
•
Both parties cannot 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, constant sound patterns—such as elongating your
words and playing externally-supplied music—may prevent the
sound-activated switches from operating properly.
•
Place the telephone on a hard surface and away from table edges.
Do not place the telephone in corners or enclosures. Do not let
obstructions come between you and the microphone. Rooms with
hard, flat surfaces that reflect sound may affect the
sound-activated switches.
•
If you are using a handset and the other party is using a
speakerphone, avoid breathing heavily into your microphone.
Avoid other sounds that may affect the distant telephone’s
sound-activated switches.
•
In some situations, such as when either you or the distant party
are in a noisy environment, you may have to lift your handset to
ensure a clear conversation.
•
When both you and the distant party use speakerphones, the
sound-activated switches can occasionally detect both voices
simultaneously, thus blocking out both voices.
