raymarine ST50+ radar: ships heading marker alignment

[MvN]

I am fitting a ST50+ radar to my boat (mint condition, hardly used) and I noticed during a dry run test, without any data connection to the rest of the navigation system, that the ship heading line is about 35d off to the heading line of the scanner. I checked the gears of the array and the reed contact seems to be nicely aligned with the 'north' of the scanner.

I went over the manual again and again and tried a 'hard reset' (no clue if it was successful) and there is a vague reference to an 'initial setup'.

Does anybody know how to correct the heading line in this old equipment?

I had one of the Raytheon (Autohelm) RL9 which I suspect is similar.
After a lot of non use, the internal coin type battery was bad which made it lose its original setup.
I soldered in a new one (not hard) and finally found the way to set it up.
Here's link to the manual which may be very similar to the one you have.
I suspect the procedure is the same.
It worked for me. See 3-10 and 3-17. Go to "setup page" and turn it on.
It's been ten years at least since I had that radar, so memory's a bit vague, but I think that's where you can adjust the heading line and save it before you exit that menu. Good luck.

Good suggestion! seems to be the same device and, oddly enough, the last chapters are not present in the ST50+ manual. In chapter 5 there is a decent explanation about how to adjust system parameters.

MvN,

Page 5-12 explains it exactly.
I'm glad I could help.
