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 and the frame around the
heart symbol has disappeared?
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. However, 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.
