My Polar FSE Heart Rate Monitor Watch arrived without a manual. It took several tries with the single button programming to figure out how the watch worked. Once this was done the watch and heart rate monitor has worked well during the last month of almost daily exercises.One caution, I am a large man and the wrist and chest bands with this watch barely fit me. On a positive note I wear glasses but not when exercising. Still I am able to read the large readout on the watch face.For the first month this has been a good heart monitor which has a watch function as well.
