User Manual

l Make sure the tracker is in contact with your skin.
l Don't wear your tracker too tight; a tight band restricts blood flow, potentially
affecting the heart-rate signal. However, the tracker should be slightly tighter
(snug but not constricting)during exercise than during all-day wear.
l 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 (about 10
seconds). You should see a heart-rate reading.
Wrist choice and dominant hand
For greater accuracy and ease of use, Alta HR needs to know which wrist you wear
it on (right or left) and which hand you consider dominant (right or left). Your
dominant hand is the one you usually write or throw with.
During setup, you're asked to choose the wrist where you're going to wear Alta HR.
Should you later decide to move Alta HR to the other wrist, change the Wrist
setting.You can also change your dominant hand at any time with the Handedness
setting. Both settings are found in the Account section of the Fitbit app.
Change the wristband
The wristband has two separate bands (top and bottom) that you can swap with
accessory bands sold separately.
