Vertical Communications 8012S manual Half-Duplex Speakerphone Guidelines

iPrimo Speakerphone Station User’s Guide

•If both you and the distant party are using full-duplex speakerphones, the sensitivity to both echo path changes and volume reduction during double-talk is doubled from the sensitivity when just one full-duplex speakerphone is involved.

Half-Duplex Speakerphone Guidelines

The speakerphone user guidelines in this section do not apply when your speakerphone is operating in full-duplex mode. However, they are applicable when operating in half-duplex mode or in “speech training” 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 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.
