In addition to exercise intensity, medications for heart
conditions, blood pressure, psychological conditions,
asthma, breathing, etc., as well as some energy drinks,
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, you can use Polar
training computers. 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. To avoid any skin
reaction to the heart rate sensor, wear it over a shirt, but
moisten the shirt well under the electrodes to ensure
flawless operation.
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.
