Vertical Communications DSU and DSU II Telephone User Manual


 
1.2.2Speakerphone User Guidelines
NOTE: The speakerphone user guidelines in this section that do not
apply to the Impact SCS model 8324F-** when it is operating
in full-duplex mode are so noted. However, when the 8324F-**
is in half-duplex mode or in “speech training” mode, all of the
following guidelines are applicable.
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. Does not apply to model 8324F-** when in full duplex
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 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.
