Electromagnetic Interference and Exercise Equipment
Disturbance may occur near high-voltage power lines, traffic lights, overhead lines of electric
railways, electric bus lines or trams, televisions, car motors, sulky computers, some motor-
driven exercise equipment, cellular phones, or at electric security gates. Microwave ovens,
computers and WLAN base stations may also cause interference when exercising with CS600.
To avoid erratic readings, move away from possible sources of disturbance.
Exercise equipment with electronic or electrical components such as LED displays, motors
and electrical brakes may cause interfering stray signals. To solve these problems, try the
following:
1. Remove the transmitter from your chest and use the exercise equipment as you would
normally.
2. Move the Training System around until you find an area in which it displays no stray
reading or does not flash the heart symbol. Interference is often strongest directly 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 Training System in this
interference-free area as much as possible.
If the Training System still does not work with the exercise equipment, it may be electrically
too noisy for wireless heart rate measurement.
