How to wear a hear rate sensor with textile strap


Polar WearLink® and Polar H7 heart rate sensors have two parts: the chest strap (models: WearLink® / WearLink®+ / Soft strap) and the WearLink/H7 connector. The heart rate sensor is worn around your chest, just below chest muscles.



Wear the heart rate sensor
1a. Moisten the plastic electrode areas on the reverse side of the strap.

1b. If the strap has textile electrodes, wet them under running water.


2. Attach the connector to the strap. Adjust the strap length fo fit tightly but comfortably around your chest.


3. Tie the strap around your chest, just below the chest muscles, and attach the hook to the other end of the strap.

4. To ensure good heart rate signal detection, check that the moist electrode areas are firmly against your skin and that the Polar logo of the connector is in a central and upright position.


Follow the care and maintenance instructions to ensure reliable measurement and maximize the life span of the heart rate sensor.
