...the cycling computer does not measure the calories?
Burnt calories are calculated only when you are wearing the transmitter and all the basic settings are done
correctly. For more information see Basic Settings (page 6).
...another person with a cycling computer or a heart rate monitor is causing interference?
See Precautions (page 47).
...the heart rate reading becomes erratic, extremely high or shows nil (00)?
• Make sure the cycling computer is no further than 1 m / 3 ft from the transmitter.
• Make sure the transmitter belt has not loosened during exercise.
• Make sure the textile electrodes in the sports apparel fit snugly.
• Make sure that the electrodes of the transmitter / sports apparel are moistened.
• Make sure the transmitter / sports apparel is clean.
• Make sure that there is no other heart rate transmitter within 1 m / 3 ft.
• Strong electromagnetic signals can cause erratic readings. For further information, see Precautions
(page 47).
• If the erratic heart rate reading continues despite moving away from the source of disturbance, slow down
your speed 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.
…Check WearLink! is displayed and your cycling computer cannot find your heart rate signal?
• Make sure the cycling computer is no further than 1 m / 3 ft from the transmitter.
• Make sure the transmitter belt has not loosened during exercise.
• Make sure the textile electrodes in sports apparel fit snugly.
• Make sure that the electrodes of the transmitter / sports apparel are moistened.
• Make sure the transmitter / electrodes in the sports apparel are clean and undamaged.
• If the heart rate measurement does not work with the sports apparel, try using a WearLink strap. If your
heart rate is detected with the strap, the problem is most probably in the apparel. Please contact the
apparel retailer / manufacturer.
• If you have done all of the above-mentioned actions, and the message still appears and heart rate
measurement does not work, the battery of your transmitter may be empty. For further information, see
Care and Maintenance (page 45).
Check Speed! is displayed?
For further information, consult Speed Sensor user manual.
...the altitude keeps changing even if I am not moving?
The cycling computer converts measured air pressure into an altitude reading. This is why changes in the
weather may cause changes in altitude readings.
…the altitude readings are inaccurate?
Your altimeter may show faulty altitude if it is exposed to external interference like strong wind or air
conditioning. In this case, try to calibrate the altimeter. If the readings are constantly inaccurate, dirt may
be blocking the air pressure channels. In this case, send the cycling computer to a Polar Service Center.
....Memory low is displayed?
Memory low is displayed when there is approximately one hour of memory space left. Once the memory
has been depleted Memory full is displayed. To free memory space, transfer exercise data to Polar
ProTrainer 5 software, and delete from the cycling computer memory.
