HEART RATE READING IS ERRATIC OR EXTREMELY HIGH
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 exercise equipment.
•Another heart rate transmitter within three feet, or one meter, may also cause abnormal heart rate readings.
