2.
Attach the rubber part to the speed sensor
(picture 3).
3.
Pass the cable ties over the speed sensor
and rubber part (picture 4). Adjust the
sensor to the front fork so that the POLAR
logo faces outwards. Adjust the ties loosely.
Do not tighten them fully yet.
4.
Attach the magnet to a spoke at the same
level as the speed sensor. There is a small
caved dot at the backside of the sensor,
which indicates the spot the magnet should
be pointing at when passing the sensor.
Fasten the magnet to the spoke and tighten
it loosely with a screwdriver. Do not tighten
it fully yet.
Fine-tune the positioning of both the magnet
and the speed sensor so that the magnet passes
close to the sensor but does not touch it. Move
the sensor towards the wheel/spokes as close as
possible. The gap between the sensor and the
magnet should be under 4 mm/0.16’’. The gap
is correct when you can fit a cable tie between
the magnet and the sensor.
Rotate the front tire to test the speed sensor.
The flashing red light on the sensor indicates
that the magnet and the sensor are positioned
correctly. Once the magnet and the speed
sensor are positioned correctly, tighten the
screw to the magnet with a screwdriver. Also
tighten the cable ties securely and cut off any
excess cable tie ends.
Before you start cycling, set the wheel size of
your bicycle into the cycling computer.
