1.3.2 Speakerphone User Guidelines
NOTE: The speakerphone user guidelines in this section do not apply
to the Impact SCS 8324F-** when it is operating in full-duplex
mode. However, when the 8324F-** is in half-duplex mode or
in “speech training” mode, the following guideline are
applicable.
• 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.
