Your Polar heart rate monitor is water resistant to 100 metres/ 330 feet. To maintain the water resistance, do not operate the buttons of the wrist receiver under water.
Heart rate measurement in a water environment is technically demanding for the following reasons:
•Pool water with a high chlorine content and seawater may be very conductive and the electrodes of Polar transmitter may get short circuited and ECG signals cannot be detected 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 ECG signal.
•The ECG 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.

Disturbances may occur near high voltage power lines, traffic lights, overhead lines of electric railways, electric bus lines or trams, televisions, car motors, bike computers, some motor driven exercise equipment, cellular phones or when you walk through electric security gates.

CROSSTALK
The Polar wrist receiver in
EXERCISE EQUIPMENT
Several pieces of exercise equipment with electronic or electrical components such as LED displays, motors and electrical brakes may cause interfering stray signals. To try to tackle these problems, relocate the Polar wrist receiver as follows:
1.Remove the transmitter from your chest and use the exercise equipment as you would normally.
2.Move the wrist receiver around until you find an area in which it displays no stray reading or flashing of the heart symbol. Interference is often worst right 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 transmitter back on the chest and keep the wrist receiver in this
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.

Exercise may include some risk, especially for those who have been sedentary. To minimise possible risks consider the following advice:
Before beginning a regular exercise program consult your doctor
•if you are over 40 years of age and have not been following a regular exercise program during the past 5 years
