How to Position the Device on the Wrist
Position the health sensor band approximately one finger width up the arm from the wrist bone. If
possible, wear the health sensor band on the non-dominant hand, as this improves the quality of
the data. The health sensor band should fit tightly but comfortably around the wrist. Make sure
the skin has direct contact with the openings for the LED/photodiodes at the center of the back of
the health sensor band.
