Speakerphone Characteristics
• 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.
Half-Duplex Speakerphone Guidelines
Note: The speakerphone user guidelines in this section do not
apply to the Impact SCS 8412F-** when it is operating in full-
duplex mode. However, when the 8412F-** is in half-duplex
mode, or in 'speech training' mode, the following guidelines are
applicable.
These guidelines are also applicable to the 8412S-** whenever it
is in speakerphone mode.
• 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 in a clear 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 must—may prevent the
sound-activated switches from operating properly.
