7. PRECAUTIONS
7.1 THE POLAR WEIGHT MANAGEMENT PRODUCT AND INTERFERENCE DURING EXERCISE
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.
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 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 does not flash 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 your chest and keep the wrist unit in this interference-free area as far as it is possible.
4. If the Polar Weight Management Product still does not work with the exercise equipment, this piece of equipment may be
electrically too noisy for wireless heart rate measurement.
Crosstalk
When in non-coded mode , the wrist unit picks up transmitter signals within 3 feet/1 meter. Simultaneous non-coded
signals from more than one transmitter can cause an incorrect readout.
