7.2 MINIMIZING POSSIBLE RISKS
WHEN EXERCISING
Exercise may include some risk, especially for those who have been
sedentary.
Before starting a regular exercise program, you are recommended
to answer the following questions for health status checking. If
the answer is yes to any of the questions, we recommend that you
consult a doctor before starting an exercise program.
• Have you been physically inactive 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, psychical conditions, asthma, breathing etc. as
well as some energy drinks, alcohol and nicotine can affect your
heart rate.
It is important to be sensitive to your body’s reactions during
exercise. If you feel unexpected pain or excessive fatigue when
exercising, it is recommended to stop the exercise or continue at a
lighter intensity.
Notice to persons with a pacemaker, defi brillator 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.
If you are allergic to any substance that comes into contact with
the skin or if you suspect an allergic reaction due to using the
product, check the listed materials in the Technical Specifi cations
chapter, page 53. To avoid any skin reaction risk with the transmitter,
wear it over a shirt. However, moisten the shirt well under the
electrodes to ensure fl awless operation.
Note: The combined impact of moisture and intense abrasion may
cause a black color to come off the transmitter’s surface, which
may stain light-colored clothes.
