C.2 Speakerphone User Guidelines
• During the echo training mode, 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 EP100G-L12/
EP100G-I12 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 endpoint.
• Raising the volume of the loudspeaker makes it easier for the
sound-activated switches in your endpoint 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 endpoint 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 endpoint on a hard surface and away from table edges.
Do not place the endpoint in corners or enclosures. Do not let
obstructions come between you and the microphone. Do not
create echo changes by moving yourself or objects within
several feet of the endpoint. 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 endpoint’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.
