Wearing
1. Comfortably tighten the band around your wrist, about 1 finger width away from your wrist bone.
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.
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.
