Hello from Texas!
Just purchased a used Nox 800 as a back up machine and for my wife to try. She love swinging but hates digging 🙂 .
The software was confirmed as updated to 3.1.3.
Each time I start it up it chatters uncontrollably and has the code "AU" showing on the screen (see attached photo) Anyone know how to solve this? I have tried everything and can't find anything on the net to quiet it down.
I made sure all connections are clean and secure, removed and cleaned coil/cover, tried each detecting mode (all chatters the same), factory reset, have tried noise canceling, ground balancing, lowering sensitivity, and keeping it away from EMI (does this at home and at the beach) and turned off my mobile phone...no fix.
Hope this can be easily fixed by a setting or perhaps maybe re-installing the 3.0 update. If not, maybe it is the coil. FYI, also have an Equinox 800 as my primary machine and NEVER experience this issue.
Any advice is greatly appreciated!
