3. Wrap the strap around your
chest and attach it to the
other side of the heart rate
monitor.
NOTE: The Garmin logo should be
right-side up.
4. Turn on the Forerunner
and bring it within range (3
meters) of the heart rate
monitor.
The heart rate icon on the Timer
page changes from ashing to
constant when the Forerunner
begins receiving data.
Be sure to move away from other
heart rate monitors while the
Forerunner is trying to “pair” with
your heart rate monitor for the
rst time. After the Forerunner
pairs with your heart rate monitor,
you can go near other heart rate
monitors. For more information
on pairing and troubleshooting,
see pages 59-60.
NOTE: If you have trouble with
erratic heart rate readings, position
the transmitter on your back instead
of your chest, or try applying
electrode gel.
