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 or when you walk through electric security gates. In some cases, mobile phones may cause interference when starting the heart rate measurement.
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 unit as follows:
1.Remove the transmitter from your chest and use the exercise equipment as you would normally.
2.Move the wrist unit 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 unit 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.
