2.Move the training device around until you find an area in which it displays no stray reading or does not flash the heart symbol. Interference is often worst directly in front of the display panel of the equipment, while the left or right side of the display is relatively free of disturbance.

3.Put the heart rate sensor strap back on your chest and keep the training device in this interference-free area as much as possible.

If the training device still does not work with the training equipment, it may be electrically too noisy for wire- less heart rate measurement. For further information, www.polar.com/support.

MINIMIZING RISKS WHEN TRAINING

Training may include some risk. Before beginning a regular training 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?

•Are you taking any blood pressure or heart medication?

•Do you have a history of breathing problems?

•Do you have symptoms of any disease?

•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 training intensity, medications for heart conditions, blood pressure, psychological con- ditions, 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 training. If you feel unexpected pain or excessive fatigue when training, it is recommended that you stop the training or continue at a lighter intensity.
