While you are trying to pair your
heart rate monitor with your
Forerunner for the rst time, move
10 m away from other heart rate
monitors.
The heart rate monitor is on standby
and ready to send data. 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.
1. Push one tab on the strap through
the slot in the heart rate monitor.
Press the tab down.
2. Wet both electrodes on the back
of the heart rate monitor to create
a strong connection between your
chest and the transmitter.
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. Press
quit or enter to exit power
save mode.
5. Bring the Forerunner within range
(3 m) of the heart rate monitor.
The heart rate icon appears
on the training mode pages.
