Note that 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.
Notice to individuals with pacemakers, defibrillators or other implanted electronic devices.
Individuals who have a
pacemaker use the Polar cycling computer at their own risk. Before starting use, we always recommend a maximal
exercise stress test under a doctor’s supervision. The test is to ensure the safety and reliability of the simultaneous use of
the pacemaker and the Polar cycling computer.
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
transmitter, 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 transmitter’s
surface, possibly staining light-colored clothes. If you use insect repellent on your skin, you must ensure that it does
not come into contact with the transmitter.
