Polar Heart Rate Monitor and Interference

Electromagnetic Interference

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 non-coded mode (mode is indicated by heart symbol without frames) of operation picks up transmitter signals within 3 feet/ 1 meter. Non-coded signals from more than one transmitter picked up simultaneously can cause an incorrect readout.

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 interference-free area as far as it is possible.
