Frequently Asked Questions
What should I do if...
...the battery symbol and Battery low is displayed?
The low battery indicator is usually the first sign of an expired battery. However, in cold conditions the low
battery indicator may appear. The indicator will disappear as soon as you return to a normal temperature.
When the symbol appears, the cycling computer sounds and backlight are automatically deactivated. For
further information on changing the battery, see Care and Maintenance (page 61).
...I do not know where I am in the menu?
Press and hold STOP until the time of day is displayed.
...there are no reactions to any buttons?
Reset the cycling computer by pressing all the side buttons simultaneously for 2 seconds. After the reset,
press the red button, Start with bike settings is displayed. You can either accept the bike settings with
OK or change the bike settings. Then Basic Settings is displayed. Set the time and date, all the rest of the
settings are saved. For more information see Basic Settings (page 9) and Measuring Wheel Size (page 8).
If you do not want to change the rest of the settings you can skip them by pressing and holding STOP. All
the exercise data is saved.
...the cycling computer does not measure the calories?
Burnt calories are calculated only when you are wearing the heart rate sensor and all the basic settings are
done correctly. For more information see Basic Settings (page 9).
...another person with a cycling computer or a heart rate monitor is causing interference?
See Precautions (page 63).
...the heart rate reading becomes erratic, extremely high or shows nil (00)?
• Make sure the cycling computer is no further than 40 m/131 ft from the heart rate sensor.
• Make sure the heart rate sensor strap has not loosened during exercise.
• Make sure the textile electrodes in the sports apparel fit snugly.
• Make sure that the electrodes of the heart rate sensor / sports apparel are moistened.
• Make sure the heart rate sensor / sports apparel is clean.
• Make sure that there is no other heart rate sensor within 40 m/131 ft.
• Strong electromagnetic signals can cause erratic readings. For further information, see Precautions
(page 63).
• 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.
