2. To achieve the optimal performance of the heart rate
sensor, make sure its back to contact with your skin.
When wearing your wristband, keep it neither too tight
nor too loose but leaving some space for the skin to
be able to breathe. Tighten the wristband before you
start to exercise and properly loosen it afterward.
Too loose
Just right
If the band can easily
move up and down the
wrist, or the heart rate
sensor cannot collect the
data, try tightening the
wristband.
The band can
comfortably fit around the
wrist.
