Speakerphone Characteristics GCA70-245
120 Comdial August, 03
Depending on the telephone line conditions and the type of speaker-
phone at the other end, it may not be possible for the 8324F-** to
operate in full-duplex mode. If the speakerphone at the other end is a
half-duplex speakerphone and both parties are in speakerphone mode,
the half-duplex speakerphone is the controlling factor, preventing the
8324F-** from operating in full-duplex mode.
8.14 Speakerphone User Guidelines
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 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.
NOTE: Pressing any button (mute, hold, etc.) on the speaker-
phone while in full-duplex mode causes the system to perform the
“speech training” test again. For example, if you press MUTE
while in full-duplex mode, when you release the call from mute, the sys
-
tem will perform the entire “speech training” test again.
