I have seen this with an Ioptron cem26. The 'meridian treatment' in the hand controller is not kept in memory and has to be set at each startup. At each startup the hand controller resets to 'when meridian flip reaches 0 degrees it will stop'.

I have to recheck it cause I never use the HC for anything. All those settings are store in it for over a year and I didn't have any issue till my last 2 sessions. The only difference was my position on a remote location that I had changed it in Kstars ( I always use the "Kstars updates all devices".
