8434 and 8434DX Voice Terminal
Speaker (Listen-only) Feature
Although the 8434 and 8434DX voice terminals are shipped from the factory with the terminal set
for the Speakerphone feature, the 8434 and 8434DX voice terminals can be optioned instead for
a 1-way, listen-only speaker. If this is the case, use the SPEAKER button on the front of the
voice terminal for turning on and off the speaker.
The Speaker (listen-only) capability allows a user to engage in a 1-way conversation with the far-
end. Specifically, the user can only listen to the far-end. To speak with the far-end, the user must
use the handset which turns off the speaker. The Speaker function may also be disabled.
MUTE button
The MUTE button disables the transmitter of the speakerphone or the handset depending on
which is activated at that time. A red light next to the MUTE button goes on when the Mute
feature is activated.
VOLUME control button
The 8434 and 8434DX voice terminals have a VOLUME ‘‘arrow’’ button. This button has several
functions. When the user is on a call using the speaker or speakerphone, the VOLUME button
controls the volume of the speaker or speakerphone, whichever is being used. When the user is
on a call using the handset, the VOLUME button controls the handset volume. When the voice
terminal is idle, the VOLUME control button adjusts the tone ringer.
When the user sets the volume for the speaker, speakerphone, handset, or the tone ringer, the
display on the voice terminal shows a ‘‘bar array’’ that indicates the volume setting.
TEST button
When the voice terminal is initially powered up, the green light next to the TEST button flashes if
the link with the PBX is not (or not yet) operational. The light changes to steady green when the
voice terminal is able to communicate with the PBX. After the voice terminal is powered up, you
can press the TEST button to test the lights and the display on your voice terminal.
