7407D, Enhanced 7407D, and 7407 Plus Voice Terminals
With the Enhanced 7407D voice terminal, the handset and Speaker capability can be used
simultaneously. If you are using a 7407 Plus, you
cannot
use the handset and speaker at the
same time.
These voice terminals are shipped with the Speakerphone setting in place, but the necessary DIP
switch setting can be changed so that the voice terminal operates with the Speaker or Spokes-
man feature instead.
MICROPHONE button (on 7407D only)
On the 7407D (7407D01B) voice terminal, the MICROPHONE button turns the speakerphone
microphone on and off.
MUTE button (on the Enhanced 7407D and 7407 Plus)
On the Enhanced 7407D (7407D02C) and 7407 Plus (7407D02D) the red MUTE button disables
the transmitter of the speakerphone or the handset depending on which is activated at that time.
VOLUME control button (on Enhanced 7407D and 7407 Plus)
The Enhanced 7407D (7407D02C) and 7407 Plus (7407D02D) voice terminals have a VOLUME
‘‘arrow’’ button. This button has a double function. When there is a call active on the speaker or
speakerphone, the VOLUME button controls the volume of the speakerphone; at all other times,
the button controls the volume of the tone ringer.
When the user sets the volume for the speaker or the tone ringer, the display on the voice termi-
nal shows a ‘‘bar array’’ that indicates the volume setting.
Self-Test (on Enhanced 7407 and 7407 Plus)
The 7407D, Enhanced 7407D (7407D02C), and 7407 Plus (7407D02D) voice terminals are
equipped with a self-test.
On the 7407D (7407D01B) voice terminal, the user can test the lights, ringer, and display by
pressing the Self-Test button under the left side of the set.
On the Enhanced 7407D (7407D02C) voice terminal, the user presses the SELECT RING button
and then the DROP button in order to initiate a self-test of the voice terminal. On the 7407 Plus
(7407D02D) voice terminal, the user presses the SELECT button and then the DROP/TEST but-
ton to start the voice terminal self-test.
During the self-test, all the lights go on, the ringer sounds, and the display character positions are
lit. On the Enhanced 7407D and the 7407 Plus voice terminals, the self-test ends when the user
releases the DROP or DROP/TEST button. On the 7407D voice terminal, the lights stay lit for a
few seconds and then go off.
