Richard, I have three Furuno radars but have never experienced that problem. Be advised that Furuno offers excellent tech support by phone, something I've taken advantage of several times because my Nordhavn carries a lot of Furuno gear. Try calling the Furuno tech support line at 360-834-9300. Or you can work through tech support online at the URL below, but that's not nearly as satisfying as talking to a real, live Furuno expert. https://www.furuno.com/en/support/ No connection with Furuno other than as a highly satisfied longtime Furuno customer. Milt Baker, Nordhavn 47 Bluewater Richard P wrote: I turned on my furuno radar today after having the boat sit on the hard for the past 9 months. The antenna rotates part way around then stops, waits a few seconds and then rotates part way round again. This repeats. Has anyone had a similar problem? During the rotation segment there is a correct echo pattern displayed.

I recall Furuno had a function called Watchman that intermittently turned on and off for a preset period of time to see if anything entered the guard zone but would not run continuously. Maybe it turned on in this setting?
