Precautions
Minimizing Possible Risks
Exercise may include some risk. Before beginning
a regular exercise program, answer the following
questions concerning your health status. If you
answer yes to any of these questions, 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?
• 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 other implanted
electronic device?
• Do you smoke?
• Are you pregnant?
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, stop or
continue at a lighter intensity.
If you have a pacemaker, defibrillator or other
implanted electronic devices, use the Polar heart
rate monitor at your own risk. Before starting use,
take 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 heart rate monitor.
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. Moisten the shirt well under the
electrodes to ensure flawless operation.
