FREQUENTLY ASKED QUESTIONS
What should I do if...
...the speed reading is 00 or there is no speed reading
while cycling?
• Check the correct position and distance of the sensor
with the magnet and the cycling computer.
• Check that you have set the correct cycling settings
in your cycling computer. For further information
please refer to the user manual of the cycling
computer in question.
• If the 00 reading appears irregularly, this may be due
to temporary electromagnetic interference in your
current surroundings.
• If the 00 reading is constant, you may have exceeded
4500 riding hours and the battery is empty.
...there are irregular speed, distance or heart rate
readings?
• Electromagnetic interference as well as interference
from other wireless cycling computers may affect
readings of speed, distance and heart rate.
• Disturbances may occur near high voltage power
lines, traffi c lights, overhead lines of electric railways,
electric bus lines or trams, televisions, car motors,
bike computers, some motor driven exercise
equipment, cellular phones, or when you walk
