Minimizing Risks When Training
Training may include some risk. Before beginning a regular training 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?
Note that in addition to training 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 training. If you feel unexpected pain or
excessive fatigue when training, it is recommended that you stop the training 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 (page 53). 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.
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 heart rate sensor’s
surface, possibly staining light-colored clothes. If you use perfume or insect repellent on your skin, you must
ensure that it does not come into contact with the training computer or the heart rate sensor.
