Siemens 300 Series - Muting the Speakerphone; Open Listening

2–16 ROLMphone 300/600 User Guide
Muting the Speakerphone
If you have a Mute key, you can press it to turn off the
microphone, so that you can carry on a conversation
in your room that the other party on your line cannot
hear.
Mute is also helpful when someone puts you on hold,
since it lets you hear your party reconnect even if
there is a high noise level in your room.

Open Listening
If you have a speakerphone, you may use your hand-
set and, at the same time, let someone nearby listen to
the conversation over the speaker. This feature is
called Open Listening. While Open Listening is
active, someone nearby can hear your conversation,
but whatever they say will not be picked up by the
speakerphone.
