Call Appearance/Feature buttons
These 28 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 10 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 8528T voice terminal is equipped with a built-in S201A-type 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; 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 terminal (or the table or desk on which the
terminal is situated) is moved to another place (even in the same room).
