Troubleshooting
If you've lost your way in the menu, press and hold the button until time of day is displayed.
If the heart rate reading becomes erratic, extremely high or shows nil (00), make sure that there are no
other heart rate transmitters within 1 m/3 ft and that the transmitter fits snugly and is moistened, clean
and undamaged.
Strong electromagnetic signals can cause erratic readings. Electromagnetic disturbances may occur near
exercise equipment with electronic components, high-voltage power lines, traffic lights, overhead lines of
electric railways, electric bus lines or trams, televisions, car motors, bike computers, some motor-driven
exercise equipment, cellular phones, or at electric security gates.
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 does not work despite the actions mentioned previously, the battery of your
heart rate sensor may be empty.
Troubleshooting Checklist
If you experience difficulties with heart rate measuremant, consider the following:
1. Is the heart rate sensor worn correctly? The belt should be worn flat and tight but comfortably against the
skin with the text visible and in upright position.
2. Make sure the electrodes of the heart rate sensor are clean and well-moistened.
3. The training computer must be within one-meter / three feet from the heart rate sensor. The training
computer picks up sensor signals within one meter / three feet.
4. Are the heart rate signals very high and abnormal? Relocating the training computer may help.
Disturbance can also be caused by other heart rate monitors or training equipment nearby (see
Precautions (page 13) for further information).
5. The chemicals in seawater and some swimming pools may affect the ECG signal pick-up. Pool water with
high chlorine content, and seawater are very conductive. The electrodes of the heart rate sensor may
short-circuit, preventing ECG signals from being detected by the heart rate sensor. Jumping into water or
strenuous muscle movement during competitive swimming may shift the heart rate sensor to a location
on the body where ECG signals cannot be picked up. The ECG signal strength is individual and may vary
depending on the individual’s tissue composition. Problems occur more frequently when measuring heart
rate in water.
6. The battery of your training computer may be low even if the low battery symbol is not yet visible.
7. The battery of your heart rate sensor may be empty.
