How to put the transmitter on
1. Moisten the electrode areas of the strap
under running water and make sure that they
are well moistened.
2. Attach the connector to the strap. Position
the connector's letter L to the word LEFT on
the strap and snap the fastener.
3. Adjust the strap length to fit snugly and
comfortably. Secure the strap around your
chest, just below the chest muscles, and snap
the second fastener.
4. Check that the wet electrode areas are firmly
against your skin and that the Polar logo of
the connector 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 unit within
1 meter/ 3 feet of your
transmitter.
3. Check that you are not near other people
that have heart rate monitors, high voltage
power lines, televisions or other sources of
electromagnetic disturbance. In some cases,
mobile phones may cause interference when
starting the heart rate measurement.
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 5 mm/ 0.2". 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. Check that you can turn the handle
bar normally and cable wires for brakes or
gearing do not catch on the sensor. Check
also that the sensor does not disturb
pedaling or the use of brakes or gearing.
