I just got me 2308 station today and on the vane there is the letters for north, south, and so on. If I mount the vane on the east side of the house so that the e is facing east, I will have problems with trees. I wanted to mount it on the west side of my house where there will be no obstructions at all. So my question is, can I unscrew the 3 small screws at the top of the wind vane and turn the top so it will point in conjunction with the letters when I mount it on the west side of the house?
