H. PRECAUTIONS
Using the Polar Heart Rate Monitor in a Water Environment
Your Polar heart rate monitor is water resistant to 160 feet/ 50 meters. To maintain the water resistance, do not operate the buttons of the wrist receiver under water.
Users measuring heart rate in a water environment may experience interference for the following reasons:
•Pool water with a high chlorine content and seawater are very conductive. The electrodes of a Polar transmitter may become short circuited which prevents EKG signals from detection by the transmitter unit.
•Jumping into the water or strenuous muscle movement during competitive swimming may cause water resistance that shifts the transmitter on the body to a location where it is not possible to pick up EKG signal.
•The EKG signal strength varies depending on the individual’s tissue composition and the percentage of people who have problems in heart rate measuring is considerably higher in a water environment than in other use.
