I have CRS- so that manual is within a very close reach to it !LOL My grands made me a plaque that states my grandmother has CRS- can't remember stuff within a heart .. LOL so that one proudly hangs in my sewing room !LOL and they are right.
I told them to always refer to the manual for their machines as every machine model is different, read the manual first then sew and refer to the manual as needed to prevent frustration.
