AT&T System 85 manual S203A Speakerphone, Mute/Auto Answer with light, Two Volume buttons

S203A Speakerphone

Mute/Auto Answer with light

This button toggles between the Mute and Auto-Answer features. When the speakerphone is on, the button functions as a Mute button; the red light is on. When the speakerphone is off, the but- ton functions as the Enable/Disable button for the Auto-Answer feature; when the Auto-Answer feature is enabled, the light flashes.

Two Volume buttons

These two nonlocking buttons are labeled with arrows. Between these two buttons is a row of 10 green lights that indicate the loudness. When the S203A is on, each depression of an up/down button causes the loudspeaker volume to be raised or lowered and an light on the right end of the string of illuminated lights to be turned on or off.

Recalibrate button

The Recalibrate button is located on the rear of the S203A Speakerphone. When this button is pressed (or when the S203A is powered up), the S203A executes an acoustical calibration of its environment. It is necessary to recalibrate the S203A each time it has been moved or its sur- roundings have been altered.
