Speaker (Listen-Only) Feature
The 8405B and the 8405D have a 1-way, listen-only speaker. The 8405B Plus and
the 8405D Plus have a two-way speakerphone; however, these two 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.
Speakerphone
The 8405B Plus and the 8405D Plus voice terminals are equipped with a built-in
2-way speakerphone. (The voice terminal can be optioned for a 1-way, listen-only
speaker instead. The system manager should have records of how this feature is
optioned.) The Speakerphone capability allows a user to engage in a hands-free
conversation with the far-end party. The speakerphone can be turned on or off
with the SPEAKER button; can be muted with the MUTE button, and the volume
can be raised and lowered with the VOLUME “arrow” button.
If the voice terminal has a SHIFT button and
Rest Spkr
appears below the
SPEAKER button, the user can access the Reset Speakerphone feature to adjust
the speakerphone for optimal performance.
NOTE:
If there is not a SHIFT button and Reset Spkr does NOT appear under the
SPEAKER button, the voice terminal will adjust to the surrounding
environment by itself. The user does not need to do anything manually.
By pressing the blue SHIFT button on the set and then the SPEAKER button (if
the user has an 8405B Plus or an 8405D Plus and 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
must
reset the speakerphone in any of three instances: whenever the voice terminal is
moved to another place (even in the same room), whenever the red light next to
the SPEAKER button is fluttering, and, when, in the unlikely event, the
speakerphone is making a squealing sound.
MUTE Button
The MUTE button is a fixed feature button with a red status light. The MUTE
button turns off the microphone of the built-in speakerphone (only on the 8405B
Plus and 8405D Plus) or the handset so that a person can converse with another
person in the room without the other party listening in.
