S201A and S202A Speakerphones
S201A and S202A Speakerphones
The S201A and S202A speakerphones are available for providing total voice terminal operation
without the use of the handset. Turning on the speakerphone is equivalent to lifting the voice ter-
minal handset when placing or answering a call. Turning off the speakerphone is equivalent to
hanging up the handset. The Mute switch temporarily cuts off transmission to the distant party
during a call. The S201A and S202A speakerphones automatically adapt to room acoustics,
thereby dramatically improving the sound quality.
