PRECAUTIONS
The Polar cycling computer displays performance indicators. It indicates
the level of physiological strain and exercise intensity. It also measures
speed and distance when cycling with a Polar speed sensor. No other use
is intended or implied.
Minimizing Possible Risks When Exercising
Exercise may include some risk. Before beginning a regular exercise
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?
• 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, it is recommended that you stop the exercise or continue at a
lighter intensity.
Notice to individuals with pacemakers, defi brillators or other
implanted electronic devices. Individuals who have a pacemaker use
the Polar cycling computer at their own risk. Before starting use, we
always recommend 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 cycling computer.
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 chapter Technical Specifi cations. To avoid
any skin reaction to 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, possibly staining
light-colored clothes.
• If you use insect repellent on your skin, you must ensure that it does
not come into contact with the transmitter.
