Heart Rate Monitor
Troubleshooting
If you have trouble pairing with
the heart rate monitor, or if your
heart rate readings are erratic, try
the following suggestions.
•
Position the Forerunner within
3 meters of the sensor while
pairing.
•
Stay far away from any other
sensors while pairing.
•
Move away from sources of
interference (see the previous
page).
•
Restart scan if your
Forerunner appears to be
paired with another sensor
(see
page
46).
•
Make sure scanning for the
heart rate monitor is enabled
(see
page
46).

•
Replace the battery.
•
Clean the sensors. Dirt and
sweat build-up on the sensors
can weaken signals.
•
Reapply moisture. Use
electrode gel, water, or saliva.
•
Make sure the heart rate
monitor is snug against your
body. If you have trouble with
erratic readings, position the
transmitter on your back.
•
Wear a cotton shirt, or wet
your shirt. Synthetic fabrics
that rub or flap against the
heart rate monitor can create
static electricity that interferes
with heart rate signals.
