Placement for all-day wear vs. exercise
When you're not exercising, wear FB422 a finger's width above your wrist bone.
For optimized heart-rate tracking while exercising:
•
During a workout, experiment with wearing your tracker higher on your wrist (2 finger
widths) for an improved fit. Many exercises, such as bike riding or weight lifting, cause you to
bend your wrist frequently, which could interfere with the heart-rate signal if the tracker is
lower on your wrist.
•
Wear your tracker on top of your wrist, and make sure the back of the device is in contact
with your skin.
•
Consider tightening your band before a workout and loosening it when you’re done. The
band should be snug but not constricting (a tight band restricts blood flow, potentially
affecting the heart-rate signal).
Handedness
For greater accuracy, you must specify whether you wear FB422 on your dominant or non-
dominant hand. Your dominant hand is the one you use for writing and eating. To start, the Wrist
setting is set to non-dominant. If you wear FB422 on your dominant hand, change the Wrist setting
in the Fitbit app:
From the Today tab
in the Fitbit app, tap your profile picture > FB422 tile >
Wrist
> Dominant
