Classroom Support - Sennheiser Wireless Microphone Not Working

There is a known bug with some of the microphones firmware that basically needs to just get the slider back in sync. Toggling the mute switch back and forth may resolve the issue.

Problem

You have a Sennheiser microphone that is not broadcasting audio to the speakers.

Environment

Classroom

Resolution

If a Sennheiser microphone is not working, try moving the mute slider from one position to the next and then back again. The microphone may act like the mute is on even when the switch is off. Toggling the switch in this manner may return it to normal function. The drawings below indicate the location of the switch.

Cause

The firmware may be out of sync with the physical toggle switch.
