Troubleshooting

If you don't know where you are in the menu, press and hold BACK until the time of day is displayed.

If there are no reactions to any buttons or the training computer displays unusual readings, reset the training computer by pressing four buttons (UP, DOWN, BACK and LIGHT) simultaneously for four seconds. All other settings but time and date are saved.

If the heart rate reading becomes erratic, extremely high or shows nil (00), make sure that there are no other heart rate sensors within 1 m/3 ft and that the strap/the textile electrodes fit snugly and are wet, clean and undamaged.

If the heart rate measurement does not work with the sports apparel, try measuring using the strap. If it works, the problem is most probably in the apparel. 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.

A cardiac event may have altered your ECG waveform. In this case, consult your physician.

If heart rate measurement fails despite the actions mentioned previously, the battery of your heart rate sensor may be empty.
