[Boatanchors] Collins 75S1 receiver question

[Gary Schafer]

That is just to mute the audio when changing the filters and detectors. 
  It will sometimes make a loud pop in the speaker audio if not muted.

Did I miss something?  The receiver works fine without the wafer so I feel this has something to do with the S line system of interconnection and operation and I don't have an S line to "crunch" the answer.
