• Warm up for 5 to 10 minutes.
• Follow the care instructions (
).
• Wear a cotton shirt or thoroughly wet both sides of the strap.
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.
Tips for Missing Running Dynamics Data
If running dynamics data does not appear, you can try these
tips.
• Make sure you have the HRM-Tri accessory.
Accessories with running dynamics have on the front of the
module.
• Make sure your Garmin device supports running dynamics.
For more information, go to
.
• Pair the HRM-Tri accessory with your Garmin device again,
according to the instructions.
• If the running dynamics data display shows only zeros, make
sure the heart rate monitor is worn right-side up.

Ground contact time appears only while running. It is
not calculated while walking.

Caring for the Heart Rate Monitor
NOTICE
A buildup of sweat and salt on the strap can decrease the ability
of the heart rate monitor to report accurate data.
• Rinse the heart rate monitor after every use.
• Hand wash the heart rate monitor after every seven uses or
one pool swim, using a tiny amount of mild detergent, such
as dishwashing liquid.
NOTE:
Using too much detergent may damage the heart rate
monitor.
• Do not put the heart rate monitor in a washing machine or
dryer.
• When drying the heart rate monitor, hang it up or lay it flat.
Linking to Fitness Equipment
ANT+ technology links your heart rate monitor to fitness
equipment so you can view your heart rate on the equipment
console.
