It operates normally if the computer displays the
heart rate after you wear the heart rate sensor.
* Even if the heart rate sensor is not
worn, a heart rate signal is trans-
mitted by rubbing both electrode
pads with your thumb. Use this as a
simplified method.

Tire circumference
You can find the tire circumference (L) of your tire size in the chart be-
low, or actually measure the tire circumference (L) of your bicycle.
• How to measure the tire circumference (L)
For the most accurate measurement, do a wheel
roll out. With the tires under proper pressure,
place the valve stem at the bottom. Mark the
spot on the floor and with the rider’s weight on
the bike, roll exactly one wheel revolution in a
straight line (until the valve comes around again to the bottom). Mark
where the valve stem is and measure the distance.
* Measure the tire to which the sensor is installed.
• Tire circumference reference table
* Generally, the tire size or ETRTO is indicated on the side of the tire.
