and ensure comfort (HRM-Fit Sports Bra Guide, page2).
2Wet the electrodes on the back of the heart rate monitor to create a strong connection between your
chest and the transmitter.
3Open the clips on the front of the heart rate monitor.
4Insert the sports bra band fabric into the center clip .
The fabric must lay flat inside the clip.
5Close the clip on to the fabric until it clicks into place.
Heart Rate Monitor Instructions 1

6Repeat steps 4 and 5 with the side clips .
As you are closing the side clips, use your other hand to lightly pull the sports bra band towards the center.
7Make sure the HRM-Fit heart rate monitor is secured in place, lays flat beneath the sports bra band, and is
compressed against the skin.
After you put on the heart rate monitor, it is active and sending data.
HRM-Fit Sports Bra Guide
The HRM-Fit heart rate monitor works best with a sports bra that has a flat band around the rib cage. Good band
compression is needed to minimize heart rate monitor movement and ensure good contact between your skin
and the electrodes so that the heart rate monitor can accurately detect your heart rate.
2 Heart Rate Monitor Instructions

Band tightness
The sports bra has medium or high support and tight compres
sion designed for running, cardio, or high-intensity workouts.
Two fingers fit snugly under the sports bra band, and you can't
easily pull the band away.
Heart Rate Monitor Instructions 3

Band and strap width
The width of the sports bra band under the bust is approximately
from 19 to 50 mm (from 0.75 to 2 in.). A long band may position
the heart rate monitor too low on the torso for accurate heart
rate. A narrow band may not have enough material to properly
clip onto the heart rate monitor.
Zipper
The sports bra does not have a zipper or other embellishment in
the front that might interfere with the clips.
4 Heart Rate Monitor Instructions

Pairing and Setup
Pairing the Heart Rate Monitor with Your ANT+®Device

Heart Rate Monitor Instructions 5

Running Dynamics
You can use your compatible Garmin device paired with the HRM-Fit heart rate monitor to provide real-time
feedback about your running form.
The heart rate monitor has an accelerometer that measures torso movement in order to calculate six running
metrics.
NOTE: To use the running dynamics features, the HRM-Fit heart rate monitor must be paired to your compatible
Garmin device using ANT+ technology. For more information, see your owner's manual.
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.
Running Pace and Distance
The heart rate monitor 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 Garmin device when connected using ANT+ technology. You can also view it on compatible
third-party training apps when connected using Bluetooth technology.
Activity Tracking
Whenever you wear the HRM-Fit heart rate monitor, it monitors your daily activity metrics. The activity tracking
feature records your step count, calories, intensity minutes, and all-day heart rate. To use this feature, you must
pair your heart rate monitor and any other Garmin devices with your Garmin Connect account (Pairing the Heart
Rate Monitor with the Garmin Connect™ App, page5).
After it is paired, the heart rate monitor sends activity data to your Garmin Connect account whenever the
monitor is awake and within range of your phone. If you wear only the heart rate monitor during an activity,
the TrueUp™ feature sends activity tracking data to the daily summary section in Garmin Connect and to your
compatible Garmin devices.
Heart Rate Storage for Timed Activities
You can start a timed activity on your compatible 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 compatible 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
transferred.
6 Heart Rate Monitor Instructions

Accessing Stored Heart Rate Data
If you save a timed activity without downloading stored heart rate data, you can download the data from the
HRM-Fit heart rate monitor later.
NOTE: Your HRM-Fit heart rate monitor stores up to 18 hours of activity history. When the heart rate monitor
memory is full, your oldest data is overwritten.
1Put on the heart rate monitor.
2From your compatible Garmin watch, select the History menu.
3Select the timed activity you saved while you were wearing the HRM-Fit heart rate monitor.
4Select Download Heart Rate.
Your Garmin watch generates a new activity file with heart rate data. You may need to manually import the new
file to your Garmin Connect account.
Linking to Fitness Equipment
You can connect your heart rate monitor to compatible fitness equipment using ANT+ or Bluetooth technology
so you can view your heart rate on the equipment console.
• Look for the ANT+LINK HERE logo on compatible fitness equipment.
• Look for the Bluetooth logo on compatible fitness equipment.

Tips for Wearing
CAUTION
Some users may experience skin irritation after prolonged use of the heart rate monitor, especially if the user
has sensitive skin or allergies. If you notice any skin irritation, remove the heart rate monitor and give your skin
time to heal. To help prevent skin irritation, ensure the heart rate monitor is clean and dry, and maintain a tight
fit to minimize heart rate monitor movement.
• Check your sports bra fit to minimize movement during activity.
The HRM-Fit heart rate monitor works best with good compression against the skin.
• Before you start an activity, jump around and stretch, and make sure the heart rate monitor is still securely
clipped to your sports bra.
• If your sports bra has underwires, make sure the clips do not close on the underwire.
• Make sure the heart rate monitor strap is clipped on so that it lays flat against the skin with no puckering.
• When attaching each side clip, lightly pull the sports bra band toward the center, click the side clip in position,
and let go of the sports bra.
Repeat with the opposite side.
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.
• Warm up for 5 to 10 minutes.
• Check your sports bra fit to ensure minimal movement during activity (HRM-Fit Sports Bra Guide, page2).
• Follow the care instructions (Caring for the Heart Rate Monitor, page11).
• 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 your Garmin device supports running dynamics.
For more information, go to www.garmin.com/runningdynamics.
• Pair the HRM-Fit accessory with your Garmin device again, according to the instructions.
• Make sure you are paired using ANT+ technology, rather than Bluetooth technology.
• If the running dynamics data display shows only zeros, make sure the accessory is worn right-side up.
NOTE: Ground contact time and balance appears only while running. It is not calculated while walking.
