I bought a used KMC-41 mic to use on my volunteer department's TK-5210, we have one other KMC-41 that works fine on the radio however we have two people working so we need another one and the department didn't want to purchase another one bought one used, unfortunately the KMC-41 I bought will not work. Nothing appears broken it is in pristine condition and when i push the orange button on the mic it will cause DIRECT 1 to appear on the screen so at least something works however when i do a radio check with the mic doesn't pick up anything. I did some digging to see if an earlier thread would solve my problem and I did see an earlier thread where someone was asking a question about programming a KMC-41, so do I need to reprogram it? Is there a way to do a factory reset? any help would be greatly appreciated.
