electrode gel to the electrodes.
• Clean the electrodes. Dirt and
sweat residue can interfere with
heart rate signals.
• Wear a cotton shirt or wet your
shirt if suitable for your activity.

against the heart rate monitor
can create static electricity that
interferes with heart rate signals.
• Move away from sources of
strong electromagnetic fields and
