Polar X9 Heart Rate Monitor User Manual


 
The combined impact of moisture and intense
abrasion may cause a black color to come off
the heart rate sensor’s surface, possibly
staining light-colored clothes. If you use
perfume or insect repellent on your skin, you
must ensure that it does not come into
contact with the heart rate sensor.
