3. EXERCISING
To measure your heart rate, you need to wear the transmitter. The wrist unit records the exercise information (date, duration, time spent in target heart rate zone, average heart rate, maximum heart rate and expended calories) during your exercise session.
Note: The default settings of the target heart rate limits are calculated according to your Basic Settings. You can learn more about target heart rate zones in the section Target Heart Rate Zone on page 46. This information will help you to exercise at the right level. For further information on how to set the target heart rate limits, see the section How to Change Settings on page 43.
3.1HOW TO PUT YOUR TRANSMITTER ON AND START RECORDING YOUR EXERCISE DATA
Keep the wrist unit within 3 feet/1 meter of your transmitter. Check that you are not near other people wearing heart rate monitors or any source of electromagnetic disturbance. For further information on interference, see the section Precautions on page 49.
1.Attach one end of the transmitter to the elastic strap.
2.Adjust the transmitter’s strap length to fit snugly and comfortably. Secure the strap around your chest, just below the chest muscles, and buckle the strap to the transmitter.
3.Lift the transmitter off your chest and moisten the two grooved electrode areas on the back. Check that the wet electrode areas are firmly against your skin and that the Polar logo is in a central, upright position.
4.Wear the wrist unit as a watch and press OK to start recording your exercise data. Your heart rate and
the heart symbol 
appear in a few seconds.
