Sekonic l758cine, resetting shutter angle?

Sorry if this isn't an appropriate board for this, so feel free to delete, but I was just wondering if anyone knows how to reset the shutter angle back to 180? I'm in f/s mode, but it continually displays "ang" which the manual says that indicates that it's something other than 180. So I attempt roll through all the angles and there doesn't seem to be a 180 option. should it be reset somewhere else?

thanks for any insight! I can't seem to figure it out.

Figured it out... ugg. So much information is packed into these old style lcds, turns out I was misunderstanding the formatting. The last zero is half the size onscreen, I thought it was a fractional number. Oh well, live and learn.

thanks anyway!
