HRM-Run™ Instructions
WARNING
See the
Important Safety and Product Information
guide in the
product box for product warnings and other important
information.
Putting On the Heart Rate Monitor
You should wear the heart rate monitor directly on your skin, just
below your sternum. It should be snug enough to stay in place
during your activity.
1
Snap the heart rate monitor module
À
onto the strap.
The Garmin
®
logos (on the module and the strap) should be
right-side up.
2
Wet the electrodes
Á
and the contact patches
Â
on the back
of the strap to create a strong connection between your chest
and the transmitter.
3
Wear the heart rate monitor with the Garmin logos facing
right-side up.
The hook
Ã
and loop
Ä
connection should be on your right
side.
4
Wrap the strap around your chest, and connect the strap
hook to the loop.
NOTE:
Make sure the care tag does not fold over.
After you put on the heart rate monitor, it is active and sending
data.
Pairing the Heart Rate Monitor with Your
Device
Before you can pair the heart rate monitor with your device, you
must put on the heart rate monitor.
Pairing is the connecting of ANT+
®
wireless sensors, like your
heart rate monitor, with a Garmin ANT+ compatible device.
NOTE:
The pairing instructions differ for each Garmin
compatible device. See your owner's manual.
• For most Garmin compatible devices, bring the device within
3 m of the heart rate monitor and use the device menu to pair
manually.
• For some Garmin compatible devices, bring the device within
1 cm of the heart rate monitor to pair automatically.
TIP:
Stay 10 m away from other ANT+ sensors while pairing.
After you pair the first time, your Garmin compatible device
automatically recognizes the heart rate monitor each time it is
activated.
Running Dynamics
You can use your compatible Garmin device paired with the
HRM-Run accessory to provide real-time feedback about your
running form. If your Garmin device was packaged with the
HRM-Run accessory, the devices are already paired.
The HRM-Run accessory has an accelerometer in the module
that measures torso movement in order to calculate three
running metrics: cadence, vertical oscillation, and ground
contact time.
NOTE:
The HRM-Run accessory is compatible with several
ANT+ fitness products and can display heart rate data when
paired. The running dynamics features are available only on
some Garmin devices.
Cadence
: Cadence is the number of steps per minute. It
displays total steps (right and left combined).
Vertical oscillation
: Vertical oscillation is your bounce while
running. It displays the vertical motion of your torso,
measured in centimeters for each step.
Ground contact time
: Ground contact time is the amount of
time in each step that you spend on the ground while
running. It is measured in milliseconds.
NOTE:
Ground contact time is not available while walking.
Troubleshooting
Tips for Erratic Heart Rate Data
If the heart rate data is erratic or does not appear, you can try
these tips.
• Reapply water to the electrodes and contact patches.
• Tighten the strap on your chest.
• Warm up for 5–10 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-Run accessory.
The HRM-Run accessory has on the front of the module.
• Make sure your Garmin supports running dynamics.
For more information, go to
• Pair the HRM-Run accessory with your Garmin again,
according to the instructions.
• If the running dynamics data display zeros, make sure the
HRM-Run module is worn right-side up.
NOTE:
Ground contact time appears only while running. It
cannot be calculated while walking.
Replacing the Heart Rate Monitor Battery
1
Use a small Phillips screwdriver to remove the four screws
on the back of the module.
2
Remove the cover and battery.
