the heart rate monitor each time it is activated.
Tips for Erratic Heart Rate Data
If the heart rate data is erratic or does not
appear, you can try these tips.
• Reapply moisture to the electrodes and
contact patch.
You can use water, saliva, or electrode
gel.
• Tighten the strap on your chest.
• Warm up for 5-1 0 minutes.
• Wash the strap after every seven uses
(page 5).
• 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 that can interfere
with your heart rate monitor.
Sources of interference may include strong
electromagnetic fields, some 2.4 Ghz
wireless sensors, high-voltage power lines,
electric motors, ovens, microwave ovens,
2.4 Ghz cordless phones, and wireless
LAN access points.
• Replace the battery (page 6).
