Garmin HRM1 User Manual

Wearing the HRM1 Heart Rate Monitor

Wear the HRM1Heart Rate Monitor directly on your skin, slightly below your breastbone. Wetting both sensors on the
back of the Heart Rate Monitor will result in optimum capture of heart rate pulses (wet with water or biogel). The strap
should fit snugly enough to remain in place during your exercise session. Proper placement of the Heart Rate Monitor is
also important for optimum capture of heart rate pulses.

Pairing the HRM1 Heart Rate Monitor with a Sports Monitoring Watch

The HRM1Heart Rate Monitor must “pair” with an ANT-enabled Sports Monitoring Watch in order to display Heart Rate
data to the user. To do this:

• Bring the HRM1Heart Rate Monitor within 10-30 inches (25-75cm) of the Sports Monitoring Watch

• Be sure to stand at least 72 inches (183cm) away from any other ANT-enabled Heart Rate Monitor

• You can be in proximity to other ANT-enabled devices

• After the HRM1Heart Rate Monitor pairs with the Sports Monitoring Watch, the heart rate icon should appear on

the watch and you may also be in proximity to other ANT-enabled devices
