Are you an instructor looking to use the PGA 31 Headset Microphone in one of the School of Veterinary Medicine Classrooms? This KnowledgeBase document is a document produced by the UW Center for Teaching, Learning & Mentoring, that describes how to use these microphones. It also has a video on connecting the microphone to the body packs you will find in rooms 2007, 2220, 2255, 2259, 2350, and 2360.
Note that in the SVM facilities, you will not need an AV or cabinet code to access the microphone body pack. Those will be located on the lecterns in each of the aforementioned rooms.
