Solution
• Make sure that the heart rate monitor is snug against your
body.
• Reapply moisture to the electrodes. Use water, saliva, or
electrode gel.
• Clean the electrodes. Dirt and sweat residue on the
electrodes can interfere with heart rate signals.
• Position the heart rate monitor on your back instead of your
chest.
• Wear a cotton shirt or wet your shirt if suitable for your
activity. Synthetic fabrics that rub or flap against the heart
rate monitor can create static electricity that interferes with
heart rate signals.
• Move away from sources of strong electromagnetic fields
and some 2.4 GHz wireless sensors, which can interfere
with your heart rate monitor. Sources of interference
may include high-voltage power lines, electric motors,
microwave ovens, 2.4 GHz cordless phones, and wireless
LAN access points.
