I don’t know that one. The best thing is to always make sure to fully document the original settings so you can find your way back! I’ve been in the same spot though, wondering if I switched one or not, before writing them down.
I searched their site and the web and didn’t find anything. It looks like the controller is either a QS-S4 or a clone of a QS-S4. But that won’t tell us what the initial settings should be.
Hopefully someone who owns one can chime in.
