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.
