Partial CMC fail

I have (3) three pan cams, and two have CMC constantly, while one does not. I am being billed for all 3. (originally only purchased for two, added a third camera) Have I accidently removed the third from working? I am not very internet saavy. 60+ yrs old lol.

60 years old and using “fail” as a noun? Hmm. :wink:
