My Daughter got a 645 music and it has allways been close to the distance and speed measured on our Myrun threadmill but suddenly it has started to measure some crasy speed and distances ?
like right now she ran 10 k on threadmill but watch measured allmost 19 km and some crasy speeds of 3m pr km (usually the watch is measuring something like 10.2 )
anyone got any idea whats wrong ? i cant find any settings that can be changed whatsoever
and it doesnt seem to help doing the threadmill calibration,next run its wrong again
