I did that before, but I don't know what the error messages mean.

 

 

I get the same two each time:

Time not established - critical (3) -  no ranging response received - T3 time-out

Date/time -  warning (5)  -  MIMO event MIMO: Stored MIMO=-1 post cfg file MIMO=-1  

 

Do you know what the error means and how to resolve?

 

Thanks
