3. Put the heart rate sensor strap back on your chest and keep the training device in this interference-free area as
much as possible.
If the training device still does not work with the training equipment, it may be electrically too noisy for wireless heart rate
measurement.
Health and 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.
l Have you been physically inactive for the past 5 years?
l Do you have high blood pressure or high blood cholesterol?
l Are you taking any blood pressure or heart medication?
l Do you have a history of breathing problems?
l Do you have symptoms of any disease?
l Are you recovering from a serious illness or medical treatment?
l Do you use a pacemaker or other implanted electronic device?
l Do you smoke?
l 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 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. If you experience any skin reaction, stop using the
product and consult your physician. Also inform Polar Customer Care about your skin reaction. 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 color to come off the heart rate sensor's or
wristband'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,
lotion, suntan/sunscreen 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.
