Hi,
When training with my 935 i get both tones and vibrations during training. For example,if an effort starts in 5 secs the watch beeps and vibrates each second before the start. The same happens when the effort is due to complete. With the 645M I get tones but no vibrations, ironic really when you consider the watch is designed to play music.
Is there a setting to turn vibrations on when counting in an effort during training?
Cheers
