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 training 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 training 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.
Your safety is important to us. The shape of the s3 stride sensor* is designed to minimize the
possibility of it getting caught in something. In any case, be careful when running with the stride
sensor in brushwood, for example.
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.
*Optional s3 stride sensor W.I.N.D. required.
