3.Put the transmitter back on the chest and keep the wrist receiver in this interference-free area as far as it is possible.

4.If the Polar heart rate monitor still does not work with the exercise equipment, this piece of equipment may be electrically too noisy for wireless heart rate measurement.

Minimizing Possible Risks in Exercising with a Heart Rate Monitor

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.

1.Have you not exercised for the past 5 years?

2.Do you have high blood pressure?

3.Do you have high blood cholesterol?

4.Do you have symptoms of any disease?

5.Are you taking any blood pressure or heart medication?

6.Do you have a history of breathing problems?

7.Are you recovering from a serious illness or medical treatment?

8.Do you use a pacemaker or another implanted electronic device?

9.Do you smoke?

10.Are you pregnant?

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 excessive fatigue when exercising, 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 an implanted electronic device use the Polar Heart Rate Monitor at their own risk. Before starting use, an exercise test under doctor’s supervision should be taken. The test is to ensure the safety and reliability of the simultaneous use of the implanted device 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.
