I took possession of a used RM100 today and it is not working.
I tried all different tubes throughout. I have a jumper in the parallel loop and exercised return/send on the serial loop.
If I turn up the module and give the master some volume I can hear an extremely faint sound that is so thin and strangely distorted that it sounds like a buzzer.
Any thoughts on what to look at next?
