+1. Align the rangefinder at infinity and it will be OK.
It is better with all cameras (especially rangefinder type) to avoid any kind of shock. Yes I can say that it happened to me more than once the rangefinder of my camera (usually old type rangefinder, like Balda Super Baldax or Certo 6) to loose it's alignment after a ride in the bag of my motorcycle. I learned this lesson very well...
