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

A or

B

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

5

 

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.

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.
