Each time you exceed the threshold value, a message appears
and the device vibrates.
Turning Off the Wrist-based Heart Rate Monitor
The default value for the Wrist Heart Rate setting is Auto. The
device automatically uses the wrist-based heart rate monitor
unless you pair an ANT+ heart rate monitor to the device.
1
From the heart rate widget, hold MENU.
2
Select Options > Status > Off.
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
À
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 logo facing right-
side up.
The loop
Á
and hook
Â
connection should be on your right
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 and sending
data.
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 (Caring for the Heart Rate
Monitor, page 9).
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.
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.
Running Dynamics
You can use your compatible fēnix device paired with the
HRM-Tri
accessory or other running dynamics accessory to
provide real-time feedback about your running form. If your fēnix
device was packaged with the HRM-Tri accessory, the devices
are already paired.
The running dynamics accessory has an accelerometer that
measures torso movement in order to calculate six running
metrics.
Cadence: Cadence is the number of steps per minute. It
displays the 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.
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 and balance are not available
while walking.
Ground contact time balance: Ground contact time balance
displays the left/right balance of your ground contact time
while running. It displays a percentage. For example, 53.2
with an arrow pointing left or right.
Stride length: Stride length is the length of your stride from one
footfall to the next. It is measured in meters.
Vertical ratio: Vertical ratio is the ratio of vertical oscillation to
stride length. It displays a percentage. A lower number
typically indicates better running form.
Training with Running Dynamics
Before you can view running dynamics, you must put on a
running dynamics accessory, such as the HRM-Tri accessory,
and pair it with your device (Pairing Your Wireless Sensors,
page 28). If your fēnix 5X was packaged with the accessory,
the devices are already paired, and the fēnix 5X is set to display
running dynamics data screens.
1
Select an option:
If your running dynamics accessory and fēnix 5X device
are already paired, skip to step 7.
If your running dynamics accessory and fēnix 5X device
are not already paired, complete all the steps in this
procedure.
