8434 and 8434DX Voice Terminal

Call Appearance/Feature Buttons

The 8434 and 8434DX voice terminals have 34 call appearance/feature buttons, each equipped with a red and a green status light. Usually, at least three of these buttons are administered as call appearances for the terminal’s primary extension number, where calls are placed and answered. The rest of the buttons can be used for more call appearances (including bridged appearances of other stations’ extensions) and features. Buttons administered for features have only their status lights active.

Message light

The red Message light goes on when a message is left for the voice terminal user. The light goes off when the user retrieves the message or when the message is erased.

Speakerphone (Listen and Speak) Feature

The 8434 and 8434DX voice terminals are equipped with a built-in speakerphone. The Speaker- phone capability allows a user to engage in a hands-free 2-way conversation with the far-end party. The speakerphone can be turned off or on with the SPEAKER button, can be muted with the MUTE button, and the volume can be controlled with the VOLUME ‘‘arrow’’ button.

The Speakerphone feature also allows the user to adjust the speakerphone for optimal perfor- mance. By pressing the SHIFT button and then the SPEAKER button (if the voice terminal is set for the Speakerphone feature), the user hears a set of tones as the speakerphone performs an acoustic test of the environment. When the tones stop, the speakerphone has finished adjusting itself and is ready for use. The user should reset the speakerphone whenever the voice terminal is moved to another place (even in the same room), whenever the red light next to the SPEAKER button is fluttering, and in the unlikely event that the speakerphone is making a squealing sound (in this last case, tones will not be heard during a call).
