Wear Model FB512
Place Model FB512 around your wrist. If you need to attach a different size wristband, or if you
purchased another wristband, see the instructions in
"Change the wristband"
.
Placement for all-day wear vs. exercise
When you're not exercising, wear Model FB512 a finger's width above your wrist bone.
For optimized heart-rate tracking while exercising:
●
During a workout, experiment with wearing the device higher on your wrist (2 finger widths) for
an improved fit. Many exercises such as bike riding or weightlifting cause you to bend your wrist
frequently, which could interfere with the heart-rate signal if the watch is lower on your wrist.
●
Wear your Fitbit device on top of your wrist, and make sure the back of the device is in contact
with your skin.
●
Consider tightening your wristband before a workout and loosening it when you’re done. The
wristband should be snug but not constricting (a tight wristband restricts blood flow, potentially
affecting the heart-rate signal).
Handedness
For greater accuracy, you must specify whether you wear Model FB512 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 Model FB512 on your dominant hand, change the Wrist setting in
the Fitbit app:
From the Today tab
in the Fitbit app, tap your profile picture > Model FB512 tile > Wrist Placement
> Dominant.
