ability to provide a heart rate reading. 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. If your tracker does not show a heart
rate reading, try relaxing your wrist and staying still briefly (about 10 seconds),
after which 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.
Using the Tap Display
Alta HR has an OLED tap display that can be oriented horizontally or vertically. You
can choose from several clock faces, each with a unique design. Single-tap the
display to flip through your stats.
