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. If necessary, you can purchase a strap extender at buy.garmin.com.
-
Wet the electrodes
on the back of the heart rate monitor to create a strong connection between your chest and the transmitter.
-
Wear the heart rate monitor with the
Garmin® logo facing right-side up.
The loop
and hook 
connection should be on your right side.
After you put on the heart rate monitor, it is active and sending data.
