My Heart Rate Monitor is Reporting Erratic Data
Typically, incorrect heart rate data originates in the Heart Rate Monitor (HRM) and not in the
device. If the device is reporting high heart rate spikes or an irregularly low heart rate there are a
few things that may be at fault.
Tips to eliminate erratic heart rate data:
Apply moisture to sensors and contact patch using water or saliva
Make sure the strap is worn snug and not allowed to slide down your body
Warm up for 5–10 minutes before an activity
Try a cotton shirt or wetting your shirt: synthetic fabrics can rub or flap against HRM
creating static electricity which can interfere with HR signals
Reposition HRM to either your side or back

Avoid strong electromagnetic fields and 2.4 GHz wireless sensors, such as high voltage
power lines, microwave ovens, 2.4 GHz cordless phones and other wireless access points
Other possible causes of erratic heart rate data:
Improper care of the Premium HRM can cause permanent damage. Review the HRM
care document for further clarification
Medicine, such as Beta blockers, and devices, such as pacemakers or implantable cardiac
defibrillators could potentially interfere with HRM readings. Consult physician regarding
this possibility and for possible solutions.
Being aware of possible troubleshooting steps and causes for erratic HRM data will help ensure
the best possible experience when using a HRM.
Using a Heart Rate Monitor While
Swimming
Garmin features multiple styles of Heart Rate Monitors. The standard Heart Rate Monitor(Hard
Strap), Premium Heart Rate Monitor (Soft Strap), HRM-Run, and HRM-Dual are notdesigned to
provide heart rate data in the water. This limitation is related to the inability to transmit the heart
rate data through the water.
These Heart Rate Monitors are designed to withstand 30 meters of water pressure, they can be
worn while swimming without causing them damage. Being worn on the chest, the Heart Rate
Monitors do not repeatedly impact the surface of the water as wrist-worn devices do.
After exiting the water, the Garmin device will begin to record heart rate data.
The HRM-Swim and HRM-Tri are designed to store heart rate data while swimming and then
send the heart rate to a compatible devices after exiting the water*. Please refer to your device's
owner manual in order to determine if it is compatible with this feature.
My Chest Heart Rate Monitor Is Not Being
Found by My Device
If you are having difficulty pairing a Garmin Chest Heart Rate Monitor (HRM) strap to your
Garmin device, please walk through the following tips:

1. Prior to wearing, wet the electrodes on the back of the HRM strap with water or electrolyte gel.
This will help establish an electrical connection between your body and the strap.
2. The HRM strap must be worn while pairing. Make sure the logo on the front of the strap is right-
side up, directly on the skin just beneath the breastbone as shown here:
3. Bring the HRM strap within 10 feet (3 meters) of the device you are pairing it with.
4. Attempt to add the HRM strap as a new sensor to the device. This is done from the device's
settings menu by selecting the option to search for all sensors. Refer to your Owner's Manual for
specific instructions.
5. If issues persist, consider replacing the CR2032 battery in the HRM if you have not done so
before
