If the chest strap is worn near sources of electromagnetic signals, these signals may be strong enough to elevate heart
rate readings. Possible sources include:
Television sets and/or antennas, cell phones, computers, cars, high voltage power lines and motor driven exer-
cise equipment.
Another heart rate transmitter within three feet, or one meter, may also cause abnormal heart rate readings.
