Question from users manual of old Autohelm ST50 Wind.
 
If anyone has a manual for for the old Autohelm ST50 wind (not the "Plus" version, which can switch true/app wind, this old one only has appearent wind indication) could please answer my question.

The Plus version has the manual on Ramyarine's site, but not this old one, and the calibration is different. Namely the direction and the unit calibration is same, but the extended calibration (Holding CAL for 12 secs). Is completely different. It shown F1 on the display, and seemingly there is nothing that I can change here.

If anyone has a manual, i would be grateful I you coud give me the calibration sequence, or maybe send a scanned copy of the manual. I have already asked Raymarine, but they couldn't help.

Here is all that is listed in the manual that I have for the non plus version:

Push and hold CAL for 2 seconds until CO is displayed. You can now adjust the pointer to match the wind direction with the rocker switch at the bottom right of the instrument.

Push and hold CAL for 2 seconds to store.

To select windspeed units;
Push and hold CAL for 5 seconds until U1 or U2 is displayed;
Push CAL within 8 seconds to change units between meters / second and knots / second.

That is all it has.

If you are showing only F1, something may wrong with your wind head.

Thanks! So it seems F1 is some undocumented stuff, as the other sequences are working, and the instuments if working too.
