ページを印刷する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.
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
À
create a strong connection between your chest and the
transmitter.

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 and sending
data.
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 Forerunner 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 Forerunner 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.
Caring for the Heart Rate Monitor
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.

NOTICE
Foot Pod
Your device is compatible with the foot pod. You can use the
foot pod to record pace and distance instead of using GPS when
you are training indoors or when your GPS signal is weak. The
foot pod is on standby and ready to send data (like the heart
rate monitor).
After 30 minutes of inactivity, the foot pod powers off to
conserve the battery. When the battery is low, a message
appears on your device. Approximately five hours of battery life
remain.
Foot Pod Calibration
The foot pod is self-calibrating. The accuracy of the speed and
distance data improves after a few outdoor runs using GPS.
Situational Awareness
Your Forerunner device can be used with the Varia Vision
device, Varia
smart bike lights, and rearview radar to improve
™
situational awareness. See the owner's manual for your Varia
device for more information.
NOTE: You may need to update the Forerunner software before
pairing Varia devices

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.
• Warm up for 5 to 10 minutes.
• Follow the care instructions
Monitor, page
6).
• 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.
Customizing Your Device
Activity Profiles
Activity profiles are a collection of settings that optimize your
device based on how you are using it. For example, the settings
and data screens are different when you are using the device for
running than for riding your bike.
When you are using a profile and you change settings such as
data fields or alerts, the changes are saved automatically as part
of the profile.
Activity Settings
These settings allow you to customize your device based on
your training needs. For example, you can customize data
screens and enable alerts and training features.
Alerts
You can use alerts to train toward specific heart rate, pace, time,
distance, cadence, and calories goals and to set run/walk time
intervals.
