Heart rate sensor
Heart rate is measured when the heart rate sensor is worn on the chest.
1. Insert the HR strap hook to a hole on the heart rate sensor, and push it until it clicks.
2. Wear the heart rate sensor with the HR strap, and adjust the length of the HR strap to
fit your chest size (under bust). Fastening the strap too tightly may cause discomfort.
3. Insert the HR strap hook to another hole on the heart rate sensor, and push it until it
clicks.
4. For removal, hold near the hole on the heart rate sensor and the hook, and twist off.
* Ensure that the rubber part of the electrode pad is in direct contact with the body.
* When your skin is dry, or wearing the heart rate sensor on top of your undershirt
may produce measurement errors.
To avoid errors, moisten the rubber part of the electrode pad.
