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.
