For contact information and all Polar Service Center addresses, visit and country-specific websites.


Polar products (training devices, activity trackers and accessories) are designed to indicate the level of physiological strain and recovery during and after exercise session. The Polar training devices and activity trackers measure heart rate and/or tell your activity. The Polar training devices with an integrated GPS show speed, distance and location. With a compatible Polar accessory the Polar training devices show speed and distance, cadence, location and power output. See for a complete list of compatible accessories. The Polar training devices with a barometric pressure sensor measure altitude and other variables. No other use is intended or implied. The Polar training device should not be used for obtaining environmental measurements that require professional or industrial precision.

Minimizing risks when exercising: Exercise may include some risk. Before beginning a regular exercise program, it is recommended that you answer the following questions concerning your health status. If you answer yes to any of these questions, we recommend that you consult a doctor before starting any training program.

  • Have you been physically inactive for the past 5 years?
  • Do you have high blood pressure or high blood cholesterol?
  • Are you taking any blood pressure or heart medication?
  • Do you have a history of breathing problems?
  • Do you have symptoms of any disease?
  • Are you recovering from a serious illness or medical treatment?
  • Do you use a pacemaker or other implanted electronic device?
  • Do you smoke?
  • Are you pregnant?

In addition to exercise intensity, medications for heart conditions, blood pressure, psychological conditions, asthma, breathing, etc., as well as some energy drinks, drugs, alcohol, and nicotine may also affect heart rate. It is important to be sensitive to your body’s responses during exercise. If you feel unexpected pain or excessive fatigue when exercising, it is recommended that you stop the exercise or continue at a lighter intensity.

Note! If you are using a pacemaker or other implanted electronic device, you can use Polar products. In theory interference to pacemaker caused by Polar products should not be possible. In practice no reports exist to suggest anyone ever having experienced interference. We cannot however issue an official guarantee on our products’ suitability with all pacemakers or other implanted devices due to the variety of devices available. If you have any doubts, or if you experience any unusual sensations while using Polar products, please consult your physician or contact the implanted electronic device manufacturer to determine safety in your case.

If you are allergic to any substance that comes into contact with your skin or if you suspect an allergic reaction due to using the product, check the listed materials in Technical Specifications. In case of any skin reaction, stop using the product and consult your physician.

The combined impact of moisture and intense abrasion may cause a black color to come off the heart rate sensor’s surface, possibly staining light-colored clothes. It may also cause a darker color to come off clothing, possibly staining lighter-colored training devices. To keep a light-colored training device glowing for years to come, please make sure the clothing you wear while training does not bleed color. If you use perfume or insect repellent on your skin, you must ensure that it does not come into contact with the training device or the heart rate sensor.

If you train in cold conditions (-20 °C to -10 °C / -4 °F to 14 °F) we recommend that you wear the training device under the sleeve of your jacket, directly on your skin.

Disturbance may occur near electrical devices and WLAN base stations. To avoid erratic reading or misbehaviors, move away from possible sources of disturbance. For further information, see
