...there is no heart rate reading (- -)?
1.Check that the electrodes of the transmitter are moistened and that you are wearing it as instructed.
2.Check that you have kept the transmitter clean.
3.Check that you are not near other people that have heart rate monitors, high voltage power lines, televisions, mobile phones or other sources of electromagnetic disturbance.
4.Have you had a cardiac event which may have altered your EKG waveform? In this case consult your physician.
...the code search was not successful?
The frame around the heart symbol will disappear. Bring the receiver up to your chest near the transmitter’s Polar logo. The receiver starts looking for a heart rate signal again. If you still do not succeed in code searching, but your heart rate is displayed and the heart symbol without a frame is flashing, you can start exercising but your wrist receiver may become disturbed by other heart rate monitors.
...heart symbol flashes irregularly?
1.Check that the wrist receiver is not further than 3 feet/ 1 meter from the transmitter.
2.Check that the elastic strap has not become loose during exercise.
3.Make sure that the electrodes of the transmitter are moistened.
4.Make sure that there is no other heart rate transmitter within 3 feet/ 1 meter.
5.Cardiac arrhythmia may cause irregular readings. In this case consult your physician.
