Muting Your Microphone or Your Speakers
Muting Your Microphone
You can mute your microphone so that no one in the meeting can hear you speak, or to ensure that you do not transmit noise (such as shuffling papers) while someone else is speaking. To mute the microphone, choose Tools - Audio - Mute My Microphone, or click 
at the top of the participants list.
To turn the microphone on again, choose Tools - Audio - UnMute My Microphone, or click 
.
Note If you are using Request Microphone mode, you must request the microphone before speaking, even if your microphone is not muted.
Muting Your Speakers
You can mute your speakers so that you cannot hear anyone in the meeting. This feature is helpful when you need to stop listening to the meeting briefly so that you can attend to other business, such as answering a telephone call. To mute your speakers so that you cannot hear anyone in the meeting, choose Tools - Audio - Mute My Speakers.
To turn the speakers on again, choose Tools - Audio - UnMute My Speakers.
Note No one else in the meeting will know that you have muted your speakers.
