Servicing your Polar Heart Rate Monitor

We recommend all service be done by an authorized Polar Service Center. Warranty does not cover any damage caused by service not authorized by Polar. If your Polar heart rate monitor is out of warranty and water resistance is not a concern, you may take your receiver to a local jeweler or battery replacement center for battery change only. Polar International Warranty.

Before you return your Polar Heart Rate Monitor for service, please check the following points then complete and print out the service repair form.

Is the transmitter belt worn correctly? The belt should be flat against the skin, with the Polar logo right side up.

Are the electrodes on the transmitter moist? Moistening the transmitter electrodes is essential for good skin contact to obtain reliable and accurate readings.

Is the transmitter clean? Regular cleaning of the electrodes is recommended - see Care and Maintenance below.

Is the receiver within a 3 foot range from the transmitter?

Are the heart rate signals very high and abnormal? Relocating the receiver may help. Check the list of sources of disturbances in this document below.

Check that there are no other transmitters within 3 feet if you have a non-coded Polar HRM. Other Polar HRMs can cause inteference.

Has the receiver battery been changed by an unauthorized party causing internal damage to the receiver? If not sealed properly, moisture can enter the receiver causing permanent damage to the internal components.

Have the buttons been pressed under water, causing leakage in the receiver?

If the receiver display is frozen, carry out global reset, if your model has that feature (see the user's manual for global reset instructions).

The chemicals in some swimming pools and seawater may effect the ECG signal pick up by the transmitter resulting in abnormal readings.

The ECG signal strength varies depending on the individual's tissue composition. The percentage of people who have problems in heart rate measuring is higher in water environment than in normal use.

If you are a heart patient, have a second person use the unit under the same conditions and see if the problem still exists. (See frequently asked questions for more information.)

Sources of electromagnetic signals can cause erratic and faulty heart rate readings. Such sources include other heart rate monitors, televisions, computers, cars, electric motors, bike computers, mobile phones, antennas, high voltage power lines, electric/invisible fences and certain motor driven exercise equipment. The problem can usually be resolved by relocating the receiver. Static build up in certain clothing can also cause interference. Abnormal heart rate readings during exercise
