Speakerphone (Listen and Speak) Feature
The 7407D, Enhanced 7407D, and 7407 Plus voice terminals are equipped with a
built in 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 (use the SPEAKERPHONE button on the 7407D, the SPEAKER
button on the Enhanced 7407D, and the SPEAKER/RESET SPKR button on the
7407 Plus), can be muted (use the MICROPHONE button on the 7407D; use the
MUTE button on the Enhanced 7407D and 7407 Plus), and the speakerphone
volume can be controlled, on the 7407D, with a slide switch, or on the Enhanced
7407D and 7407 Plus, with the VOLUME “arrow” button.
The 7407 Plus (7407D02D) voice terminal has an S201A-type speakerphone
which allows the user to adjust the speakerphone for optimal performance. By
pressing the SELECT button and then the SPEAKER/RESET SPKR 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 green light next to the
SPEAKER/RESET SPKR button is fluttering, and in the unlikely event that the
speakerphone is making a squealing sound.
Speaker (Listen-only) Feature
The 7407 Plus voice terminal can be optioned for the Speakerphone (listen and
speak) or the Speaker (listen-only) feature. The Enhanced 7407D voice terminal
can be set for the Speakerphone or the Spokesman feature. (With the latter
feature, the user can use the speaker and the handset simultaneously.) In order to
turn on and off the speaker, use the SPEAKER button on the Enhanced 7407D, or
the SPEAKER/RESET SPKR button on the 7407 Plus.
