Getting to know your Fitbit Model FB407
Wearing your tracker
Your Fitbit Model FB407 should be worn on your wrist. While it may track stats such as steps and floors
when placed in a pocket or backpack, it is most accurate on the wrist. For all-day wear, your Fitbit Model
FB407 should usually rest a finger’s width below your wrist bone and lay flat (as you’d normally wear a
watch).
As with all heart-rate tracking technology, whether a chest strap or a wrist-based sensor, accuracy is
affected by personal physiology, location of wear, and type of movement. In other words, not every
person will get a perfectly accurate reading with every type of exercise. For best heart rate accuracy keep
these tips in mind:
1.
Experiment with wearing the tracker higher on your wrist during exercise. Because blood flow in
your arm increases the farther up you go, moving the tracker up a couple inches can improve the
heart rate signal. Also, many exercises such as spinning cause you to bend your wrist frequently,
which is more likely to interfere with the heart rate signal if the tracker is lower on your wrist.
2.
Do not wear your tracker too tight; a tight band restricts blood flow, potentially affecting the heart
rate signal. That being said, the tracker should also be slightly tighter (snug but not constricting)
during exercise than during all-day wear.
3.
With high-intensity interval training or other activities where your wrist is moving vigorously and
non-rhythmically, the movement may prevent the sensor from finding an accurate heart rate.
Similarly, with exercises such as weight lifting or rowing, your wrist muscles may flex in such a
way that the band tightens and loosens during exercise. Try relaxing your wrist and staying still
briefly (about 10 seconds), after which you should see an accurate heart rate reading.
Specifying dominant or non-dominant hand
To improve the accuracy of your Fitbit Model FB407, we ask that you specify whether you’re wearing it
on the wrist of your dominant or non-dominant hand. Your dominant hand is the hand you use for most
day-to-day activities, such as writing or throwing a ball. You can specify this setting in the Fitbit app or in
the fitbit.com dashboard.
To make this choice using the fitbit.com dashboard:
1.
Log in to fitbit.com.
2.
Click the
gear icon
in the top-right corner of the dashboard.
3.
