Speakerphone User Guidelines - Comdial DSU II User Manual

Speakerphone Characteristics
NOTE: Pressing any button (mute, hold, etc.) on the speakerphone 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 system will perform the entire "speech training"
test again.

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, con-
stant sound patterns—such as elongating your words and playing exter-
nally-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 conversa-
tion.
· When both you and the distant party use speakerphones, the sound-activated
switches can occasionally detect both voices simultaneously, thus blocking
out both voices.
