Putting On the HRM‍-Dual Heart Rate Monitor

NOTE: If you do not have a heart rate monitor, you can skip this task.

If you have another Garmin® heart rate monitor, see your heart rate monitor owner's manual.

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. Snap the heart rate monitor module Callout number 1 onto the strap.

    The Garmin logos on the module and the strap should be right-side up.

  2. Wet the electrodes Callout number 2 and the contact patches Callout number 3 on the back of the strap to create a strong connection between your chest and the transmitter.

  4. Bring the device within 3 m (10 ft.) of the heart rate monitor.

After you put on the heart rate monitor, it is active and sending data.

TIP: If the heart rate data is erratic or does not appear, see the troubleshooting tips (Tips for Erratic Heart Rate Data).
