POLAR FT4 - Manual (Page 14)

If the abnormal reading continues despite moving away from the source of disturbance, slow down and
check your pulse manually. If you feel it corresponds to the high reading on the display, you may be
experiencing cardiac arrhythmia. Most cases of arrhythmia are not serious, but consult your doctor
nevertheless.
If heart rate measurement does not work despite the actions mentioned previously, the battery of your
transmitter may be empty.
A cardiac event may have altered your ECG waveform so that the transmitter is not able to detect it. In this
case, consult your physician.
