Posted same, Thanks!I've attached my H180 manual and also sent it to the manual forum. Iceberg's document was for the Ajak Geo-Sync, which was a little brother of the H180. They seem very similar.
I was able to set my declination to 5.5 degrees, which is within a few-hundredths of the correct value for here. I don't have my notes from measuring the holes anymore, and I was only trying to find the right combination for my latitude. From what I recall, it seemed you could step in at least 0.5 degree increments.
