Using The Speaker and The Microphone
Muting The Microphone
To mute the microphone so that you can hear the other party but they cannot
hear you (this does not put them on hold), press (MUTE). To return to the call,
press (MUTE).
Group Listen Using The Speaker
The “Group Listen” feature allows you to transmit a conversation over the
speaker while using a handset or headset. This allows other people in the room to
listen to the conversation. However, the microphone remains disabled so that
only you can speak through the handset or headset.
This feature cannot be used on a handsfree call. You must be on a call using the
handset or a headset before entering the feature code.
To turn the group listen feature on or off during a call, while on a call using the
handset or a headset, press (∞) and dial 312
Note
If you are using the handset, the SPKR key lamp will remain unlit, even
though the speaker is on. This allows you to place the call into handsfree mode at
any time during the call by pressing the SPKR key. If you are using a headset, the
SPKR key lamp is lit. Pressing the SPKR key will disconnect the call.
