Message Light
The red Message light goes on when a message is left for the user. This light
goes off when the user retrieves the message.
Call Appearance/Feature buttons
These 20 buttons are devoted
either
to handling incoming and outgoing calls (call
appearances) and are labeled with the exchange (numbers) and extension
number
or
they can be used as feature buttons to access voice features such as
Call Forward or Send All Calls; these are labeled with the feature name. Each of
these 20 call appearance/feature buttons has a red light, which indicates the
selected line, and a green light which indicates the status of that line or feature.
REDIAL button
With the Redial feature, the user can redial the telephone number last dialed from
the dial pad. (The handset must be off-hook, or the speaker must be active.) Up to
37 digits can be redialed.
Speakerphone (Listen and Speak) Feature
The 8520T voice/data terminal is equipped with a built-in S201A-type
speakerphone. The Speakerphone 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; it can be muted with the MUTE button,
and the volume can be controlled with the VOLUME “arrow” button.
With the softkeys, the user can adjust the speakerphone for optimal performance.
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/data terminal (or the table or desk on which the terminal is situated) is
moved to another place (even in the same room).
