Receivers have a range of 250 feet and will interfere with other receivers on the same channel within their range. If in a lecture hall, the channel number will be posted on the PC monitor. A sign indicating the channel number will also be posted facing the students. If you plan to use your own computer and TurningPoint receiver please change the channel to another value.
Instructors using their own receiver and laptop should select a channel in the 74-82 range.
