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.
