4. There are two spoke magnet options.
You only need to install one of
them. Check which of the magnets fits
the spoke of your bike best. One (A) is
installed by rotating it around the spoke
before putting the metal cover on,
another (B) by tightening the screw. The
magnet must be facing the speed sensor.
5. Fine-tune the positioning of both the
magnet and the sensor so that the
magnet passes the sensor closely but
does not touch it. The maximum distance
between the speed sensor and the spoke
magnet should be 0.2"/ 5 mm. Once
positioned correctly, tighten the cable
ties securely and cut off any excess cable
tie ends.
Your safety is important to us. While
riding your bike, please keep your eyes
on the road to prevent possible accidents
and injury. Before riding your bicycle,
check that you can turn the handlebars
normally and cable wires for brakes or
gearing do not catch on the sensor.
Check also that the sensor does not
disturb pedalling or the use of brakes or
gearing.
How to Put the Transmitter On
1. Attach the transmitter to the elastic strap.
2. Adjust the strap length to fit snugly and
comfortably. Secure the strap around your
chest, just below the chest muscles, and
buckle it.
3. Lift the transmitter off your chest and
moisten the grooved electrode areas
on the back.
4. Check that the wet electrode areas are firmly
against your skin and the Polar logo is in a
central, upright position.
How to Start Measuring Your Heart Rate
1. Begin with the display that shows
the time of day.
2. Keep the wrist receiver within
3 feet/ 1 meter of your transmitter.
3. Check that you are not near people that have
heart rate monitors, high voltage power lines,
televisions, mobile phones or other sources of
electromagnetic disturbance.
