POLAR HEART RATE MONITOR AND INTERFERENCE
ELECTROMAGNETIC INTERFERENCE
Disturbances may occur near high voltage power lines, televisions, cars, bike computers, some exercise equipment or cellular phones.
CROSSTALK
The
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 Polar Transmitter from your chest and use the exercise equipment as you would normally.
2.Move the 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 Receiver in this interference free area.
4.If the Polar Heart Rate Monitor still does not work with the exercise equipment, this piece of equipment may be too noisy electrically for wireless heart rate measurement.
Notice for persons with pacemakers
Persons who have a pacemaker use the Polar Heart Rate Monitor at their own risk. Before starting use, we always recommend an exercise test under doctor’s supervision. The test is to ensure the safety and reliability of the simultaneous use of the pacemaker and the heart rate monitor.

Frequently
Asked
Questions
WHAT SHOULD I DO IF...
...THERE IS NO HEART RATE READING?
1.Check that the elastic strap is snug enough.
2.Check that the electrodes of the Polar Transmitter are moistened and that you are wearing it as instructed.
3.Check that you have kept the Polar Transmitter clean.
Care and maintenance.
4.Check that there are no sources of electromagnetic radiation in the close vicinity of the Polar Wrist Receiver,
such as TV sets, cellular phones, CRT monitors etc.
Precautions.
5.Have you had a cardiac event which may have altered your ECG waveform? In this case consult your physician.
...HEART SYMBOL FLASHES IRREGULARLY?
1.Check that your Polar Wrist Receiver is inside the transmission range and not further that 1 metre/ 3 feet from the Polar Transmitter you are wearing.
2.Check that the elastic strap has not become loose during exercise.
3.Make sure that the electrodes of the Transmitter are moistened.
4.Make sure that there is no other heart rate transmitter within the reception range (1 metre/ 3 feet). 
Precautions/
Crosstalk.
5.Cardiac arrythmia may cause irregular readings. In this case consult your physician.
