The Polar CS speed Sensor W.I.N.D. is designed
to measure speed and distance when cycling.
No other use is intended or implied.
The latest version of this user manual can be
downloaded at www.polar.fi/support.
Please follow the pictures on the front cover.
Product Elements
1. Polar bike mount / Polar dual lock bike
mount (picture 1 A). For instructions on the
bike mount installation, refer to the user
manual of Polar training computer in
question.
2. Speed sensor, rubber part and spoke
magnet (picture 1 B).
Installing the Polar Speed Sensor
For a video tutorial, go to
http://www.polar.fi/en/support/video_tutorials.
To install the speed sensor and spoke magnet,
you will need cutters and a cross-head
screwdriver.
1. It is recommended to install the speed
sensor on the front fork (as in picture 1) of
your bicycle. Do not install the speed
sensor on the seat stay if the (optional)
power sensor is mounted.
2. Attach the rubber part to the speed sensor
(picture 2).
3. Pass the cable ties over the speed sensor
and rubber part (picture 3). 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 Polar training computer.

Speed Sensor Teaching
Your new speed sensor must be introduced to
your Polar training computer in order to receive
speed and distance data. This enables training
in a group without interference from other
sensors.
The Polar training computer and sensor that
came with the product set have already been
synchronized but teaching is necessary when
you start using a new sensor.
For further information on teaching, refer to the
user manual of Polar training computer in
question.
Care and Maintenance
Keep the speed sensor clean. Clean it with a mild soap
and water solution and rinse off with clean water. Dry it
carefully with a soft towel. Never use alcohol or any
abrasive material such as steel wool or cleaning
chemicals. Do not immerse the speed sensor in water.
Your safety is important to us. Make sure that you can
turn your handlebars normally and that the cable wires
for brakes or gears do not catch the bike mount or the
sensor. Also, make sure that the sensor does not
disturb pedaling or using the brakes or gears. While
riding your bike, keep your eyes on the road to prevent
possible accidents and injury. Avoid hard hits as these
may damage the sensor.

Speed Sensor Battery
Contact your authorized Polar Service Center for a
replacement of speed sensor. Polar recycles used
sensors. Please see the separate Polar Customer
Service Card for details.
Frequently Asked Questions
What should I do if...
...the speed reading is 0.0 or there is no speed reading
while cycling?
• Make sure the position and distance of the sensor to
the magnet are appropriate.
• Check that you have activated the speed function in
the Polar training computer. For further information,
see Speed Sensor Teaching.
• If the 0.0 reading appears irregularly, this may be
due to temporary electromagnetic interference in
your current surroundings.
• If the 0.0 reading is constant, you may have
exceeded 3000 riding hours and the battery is
empty.
...there are irregular speed, distance or heart rate
readings?
• Disturbance may occur near microwave ovens and
computers. Also WLAN base stations may cause
interference when training with Polar speed sensor
W.I.N.D. To avoid erratic reading or misbehaviors,
move away from possible sources of disturbance.
