Unmute and mute the ceiling microphone from the Classroom Touch Panel

Not all classrooms will the same colored indicator to show whether the microphones are muted. Some rooms have a red/green indicator, others have a gray/black indicator, and others do not have a colored indicator at all. When the "Mute" button is red or gray, the microphones are muted.

If the microphones are still not picking you up, try pressing "Unmute" and try again.
