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 If necessary, attach the strap extender to the heart rate
monitor.
2
Wet the electrodes on the back of the heart rate monitor to
create a strong connection between your chest and the
transmitter.
3
Wear the heart rate monitor with the Garmin
right-side up.
The loop and hook
side.
4 Wrap the heart rate monitor 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, storing, 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+
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-Tri accessory to provide real-time feedback about your
™
running form. If your Garmin device was packaged with the
HRM-Tri accessory, the devices are already paired.

The HRM-Tri 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-Tri 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.

Pool Swimming

Hand wash the heart rate monitor after exposure to chlorine or
other pool chemicals. Prolonged exposure to these substances
can damage the heart rate monitor.
The HRM-Tri accessory is designed primarily for open water
swimming, but it can be used occasionally for pool swimming.
The heart rate monitor should be worn under a swim suit or
triathlon top during pool swimming. Otherwise, it may slide down
your chest when pushing off the pool wall.
Heart Rate While Swimming
The heart rate monitor records and stores your heart rate data
while swimming. Heart rate data is not visible on compatible
Garmin devices while the heart rate monitor is underwater.
You must start a timed activity on your paired Garmin device to
view stored heart rate data later. During rest intervals when out
of the water, the heart rate monitor sends your average and
maximum heart rate for the previous interval, and your real-time
heart rate, to your Garmin device.
Your Garmin device automatically uploads stored heart rate data
when you save your timed swim activity. Your heart rate monitor
must be out of the water, active, and within range of the device
(3 m) while data is uploaded. Your heart rate data can be
reviewed in the device history and on your Garmin Connect
account.
Data Storage
The heart rate monitor can store up to 20 hours of data in a
single activity. When the heart rate monitor memory is full, your
oldest data is overwritten.
You can start a timed activity on your paired Garmin device, and
the heart rate monitor records your heart rate data even if you
move away from your device. For example, you can record heart
rate data during fitness activities or team sports where watches
cannot be worn. Your heart rate monitor automatically sends
your stored heart rate data to your Garmin device when you
save your activity. Your heart rate monitor must be active and
within range (3 m) of the device while data is uploaded.
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 (if
applicable).
• Tighten the strap on your chest.
