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.
