My boss has some legacy Shure wireless microphone systems that are no longer FCC legal. At the moment I'm trying to test a Shure UC4-UB wireless microphone receiver for use with a wireless handheld cardioid or Lavalier microphone, but I need to know how to change its group and channel. I can't find the user guide on Shure's website. I turned two recessed Phillips screws that change the only value displayed, but the group and channel aren't displayed separately. I'm throwing darts blindfolded. I would be grateful if anyone could help me. Thank you.
