Wear FB417
Place FB417 around your wrist. If you need to attach a different size wristband, or if you
purchased an accessory wristband, see the instructions in "Change the wristband" on page 9.
Placement for all-day wear vs exercise
When you're not exercising, wear FB417 a finger's width above your wrist bone.
For optimized heart-rate tracking while exercising:
• We recommend wearing FB417 higher on your wrist during exercise for an improved fit
and more accurate heart-rate reading. Many exercises, such as bike riding or weight
lifting, cause you to bend your wrist frequently, which can interfere with the heart-rate
signal if the tracker is lower on your wrist.
• Make sure the tracker is in contact with your skin.
• Don't wear your tracker too tight; a tight wristband restricts blood flow, potentially
affecting the heart-rate signal. The tracker should be slightly tighter (snug but not
constricting) during exercise.
• With high-intensity interval training or other activities where your wrist is moving
vigorously and non-rhythmically, the movement may limit the sensor's ability to provide
a heart-rate reading. If your tracker doesn't show a heart-rate reading, try relaxing your
wrist and staying still briefly.
Handedness
For greater accuracy, you must specify whether you wear FB417 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 FB417 on your dominant hand, change the
Wrist setting in the Fitbit app.
