NOTE:
The heart rate monitor works with the Forerunner 305 only.
Wear the heart rate monitor directly on your skin, just below your
breastplate. It should be snug enough to stay in place during your run.
To position the heart rate monitor:
1. Push one tab on the strap through the slot in the heart rate monitor.
Press the tab down.
