Group Listening Mode
A special speaker phone mode has been implemented which allows a person to talk into the
handset microphone while the speaker is enabled so that all people in the room can hear the
incoming voice. This will facilitate a speaker phone like conversation but without the usual
inconvenience where the speaker cuts out when the microphone is active. This is useful when
only one person is talking but others are listening.
Entering the Group Listening mode is accomplished by simply pressing the SPKR key while
talking in the handset mode. This will enable the handset microphone and disable the microphone
in the “speaker phone”. The Group Listening mode is ended by either pressing the SPKR key
which enables a private handset conversation or by placing the handset on hook which enables a
full speaker phone conversation.
