Exercise may include some risk, especially for those who have been
sedentary.
Before starting a regular exercise program an individual is recommended to
answer to the following questions for health status checking. If the answer
is yes to any of the questions, we recommend to consult a doctor before
starting an exercise program.
• Have you not exercised for the past 5 years?
• Do you have high blood pressure?
• Do you have high blood cholesterol?
• Do you have symptoms of any disease?
• Are you taking any blood pressure or heart medication?
• Do you have a history of breathing problems?
• Are you recovering from a serious illness or medical treatment?
• Do you use a pacemaker or another implanted electronic device?
• Do you smoke?
• Are you pregnant?
Note that in addition to exercise intensity, medications for heart, blood
pressure, psyche, asthma, breathing etc. as well as some energy drinks,
alcohol and nicotine, can affect heart rate.
It is important to be sensitive to your body’s reactions during
the exercise. If you feel unexpected pain or tiredness regarding your
exercise intensity level, it is recommended to stop the exercise or
continue at a lighter intensity.
If you are allergic to any substance that comes into contact
with the skin, check the Polar heart rate monitor materials from the
“Technical specifications” chapter. It is recommended that you wear
the transmitter against your bare skin to ensure flawless operation.
However, if you wish to wear the transmitter over a shirt, moisten the
shirt well under the electrodes.
Notice to persons with pacemakers, defibrillator or other
implanted electronic device. Persons who have a pacemaker use the
Polar heart rate monitor at their own risk. Before starting use, we
always recommend an exercise test under doctor’s supervision. The test
is to ensure the safety and reliability of the simultaneous use of the
pacemaker and the heart rate monitor.
The combined impact of moisture and intense abrasion may cause a
black color, which might stain light-colored clothes especially, to come
off the transmitter's surface.
