Introducing The LCD Speakerphone

1.2Using Your Speakerphone

When using your speakerphone, the microphone and loudspeaker are farther away from you than when you use a handset. Both the signal from the loudspeaker and the signal to the microphone must be strengthened. When microphones and loudspeakers are close together (such as in a speakerphone), additional amplification typically generates a ringing sound (public address systems do this if the volume is too high or the microphone is too close to a loudspeaker).

NOTE: The 8324F-** speakerphone can function in the full-duplex or half-duplex mode. Both sets of guidelines (section 1.2.1 and section 1.2.2) are applicable to the 8324F-**.

The 8012S-**, 8024S-**, 8324S-**, and 8312S-** speakerphones only function in the half-duplex mode—only section 1.2.2, Speakerphone User Guidelines, apply to these telephones.
