Pairing Your Wireless Sensors
Before you can pair, you must put on the heart rate
monitor or install the sensor.
The first time you connect a wireless sensor to your
watch using ANT+ or Bluetooth technology, you must pair
the watch and sensor. If the sensor has both ANT+ and
Bluetooth technology, Garmin recommends that you pair
using ANT+ technology. After they are paired, the watch
connects to the sensor automatically when you start an
activity and the sensor is active and within range.
1 Bring the watch within 3 m (10 ft.) of the sensor.
NOTE: Stay 10 m (33 ft.) away from other wireless
sensors while pairing.
2 Hold MENU.
3 Select Sensors & Accessories > Add New.
TIP: When you start an activity with the Auto Discover
option enabled, the watch automatically searches for
nearby sensors and asks if you want to pair them.
4 Select an option:
• Select Search All Sensors.
• Select your sensor type.
After the sensor is paired with your watch, the sensor
status changes from Searching to Connected. Sensor
data appears in the data screen loop or a custom
data field. You can customize the optional data fields
(
Customizing the Data Screens, page 23
).
HRM-Pro Running Pace and Distance
The HRM-Pro series accessory calculates your running
pace and distance based on your user profile and the
motion measured by the sensor on every stride. The heart
rate monitor provides running pace and distance when
GPS is not available, such as during treadmill running.
You can view your running pace and distance on your
compatible D2 Mach 1 watch when connected using
ANT+ technology. You can also view it on compatible
third-party training apps when connected using Bluetooth
technology.
The pace and distance accuracy improves with
calibration.
Automatic calibration: The default setting for your watch
is Auto Calibrate. The HRM-Pro series accessory
calibrates each time you run outside with it connected
to your compatible D2 Mach 1 watch.
NOTE: Automatic calibration does not work for indoor,
trail, or ultra run activity profiles (
Running Pace and Distance, page 58
).
Manual calibration: You can select Calibrate & Save after
a treadmill run with your connected HRM-Pro series
accessory (
Calibrating the Treadmill Distance, page 10
).
Tips for Recording Running Pace and Distance
• Update your D2 Mach 1 watch software (
).
• Complete several outdoor runs with GPS and your
connected HRM-Pro series accessory. It's important
that your outdoor range of paces matches your range
of paces on the treadmill.
• If your run includes sand or deep snow, go to the
sensor settings, and turn off Auto Calibrate.
• If you previously connected a compatible foot pod
using ANT+ technology, set the foot pod status to Off,
or remove it from the list of connected sensors.
• Complete a treadmill run with manual calibration
(
Calibrating the Treadmill Distance, page 10
).
• If automatic and manual calibrations don't seem
accurate, go to the sensor settings, and select HRM
Pace & Distance > Reset Calibration Data.
NOTE: You can try turning off Auto Calibrate, and
then manually calibrate again (
).
Running Dynamics
Running dynamics is real-time feedback about your
running form. Your D2 Mach 1 watch has an
accelerometer to calculate five running form metrics. For
all six running form metrics, you must pair your D2 Mach 1
watch with the HRM-Pro series accessory or other running
dynamics accessory that measures torso movement. For
more information, go to

Sensor Type
Description
Cadence
Watch or compatible
accessory
Cadence is the number of steps per minute. It displays the total steps
(right and left combined).
Vertical oscilla
tion
Watch or compatible
accessory
Vertical oscillation is your bounce while running. It displays the vertical
motion of your torso, measured in centimeters.
Ground contact
time
Watch or compatible
accessory
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
Compatible accessory
only
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.
