Sturdy engine controls - older Broward

I’ve got an issue with my Sturdy engine controls on a 1997 Broward.

The system comes on but I can’t take control at any of the stations.

All I get is both the red “take command” light and the green “sync” light flash simultaneously at all stations.

Anyone know what it’s trying to tell me?

Of course I have no manual on board and so far I can’t find any answers on the inter web.

Worked through it with Sturdy.

The “take command” button at one station is bad.

Once I unplugged the lead for the bad one from the distribution box the other stations came back on line normally.

Interestingly, when I first told them I thought I had a bad button at one of the stations they said that wouldn’t be causing the problem.

Then when I told them the system was working correctly with the station with the bad button disconnected, they said, “yeah a stuck button could cause that”. !?
