ANT+ Sensor Troubleshooting
Problem Solution
I have a third-party
ANT+ sensor.
Make sure that it is compatible with the Forerunner
( www.garmin.com/intosports ).
I changed the battery in
my accessory.
You must pair the sensor to your Forerunner again ( page 22 ).
The heart rate data is
inaccurate or erratic.
• Make sure that the heart rate monitor is snug against your body.
• Warm up for 5–10 minutes.
• Reapply moisture to the electrodes and contact patch. Use water,
saliva, or electrode gel.
• Wash the strap after every seven uses ( page 42 ).
• 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.
