If the heart rate measurement does not work with the sports apparel, try using the strap. If it works, the
problem is most probably in the apparel. Check that the electrode areas of the apparel are clean. Before
washing the apparel, check the washing instructions. If the heart rate measurement still does not work,
please contact the apparel retailer/manufacturer.

Strong electromagnetic signals can cause erratic readings. Electromagnetic disturbances may occur near
high-voltage power lines, traffic lights, overhead lines of electric railways, electric bus lines or trams,
televisions, car motors, bike computers, some motor driven training equipment, cellular phones, or at
electric security gates. To avoid erratic readings, move away from possible sources of disturbance.

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.
