How can I mark a lap manually in the Polar app on M600?
You can mark a lap manually during training by pressing the front button. Marking the first manual lap will create a manual lap view to your Polar app for that training session. The manual lap data is saved and synchronized to Flow app and Flow web service after exercise.
You can also use the automatic lap setting. In the Polar Flow web service, edit the sport profile settings under Basics, and set the Automatic lap either to Lap distance or Lap duration. If you choose Lap distance, set the distance after which each lap is marked. If you choose Lap duration, set the duration after which each lap is marked.
