Speaker (Listen-only) Feature
The 8520T voice/data terminal can be optioned for the Speakerphone (listen and
speak)
or
the Speaker (listen-only) feature. (The terminal is shipped with the
Speakerphone setting in place.)
The Speaker (listen-only) capability allows a user to engage in a one-way
conversation with the far-end. The user can only listen to the far-end; the user is
not able to transmit his voice over the speaker. Use the SPEAKER button on the
front of the terminal for turning on and off the speaker or speakerphone. To speak
with the far-end, the user must use the handset. Lifting the handset turns off the
speaker.
MUTE button
While on a call, the user can press the MUTE button (the red light next to the
button goes on), so the user can converse with someone in the same room
without the other party hearing the conversation. The user is placed in listen-only
mode. To disable the feature, the user presses the MUTE button a second time
(the red light goes off). The Mute function works only with the speakerphone and
the handset.
EXIT button
The EXIT button is used for exiting a softkey feature and returning to the
user-selected Home Screen. The top two lines again show you the time and date
and any relevant system information.
VOLUME control button
When the user is on a call using the speakerphone, the VOLUME “arrow” button
raises or lowers the volume on the speakerphone. Likewise, when the user is on a
call using the handset, the VOLUME control button changes the receive level of
the handset. When the handset is on-hook and the speakerphone is off, this
button raises or lowers the ringer volume or tones such as the confirmation or
error tone.
Softkeys
The 10 unlabeled buttons located on both sides of the display correspond to
words on the display screen. Softkeys are used along with display control keys to
access the following features:
■ Setting the clock
■ Setting the speakerphone
■ Adding, editing, and deleting the numbers and associated names (and
optional group names) in the voice terminal Directory
■ Organizing your Directory in alphabetical order or by group name,
renaming a group, and moving Directory entries from one group into
another
