My XLR Sniffer error codes don't match what you have on the website. Why is that?
Before our current version of the XLR Sniffer/Sender we had a version assembled by Audio Control. These units will usually say "Made for Rat Sound by Audio Control" or something along those lines.
The second version was made for Rat but features "a, b, c" on the Sniffer end for error reporting. (Gen1 error code attached)
The testing circuit for these models has a different error code readout. If you need to print out the error codes you can download the PDF attached to this article.
