Congratulations! The Polar s3 stride sensor
W.I.N.D. is the best choice for improving your
running technique and efficiency. Using
sensitive inertial sensors to track the position of
the foot, it is immune from signal dropout, and
gives accurate and highly responsive speed,
distance, leg cadence and stride length
measurements.

Please follow the pictures on the front cover.

Install Stride Sensor Battery
Before using the s3 stride sensor for the first
time, insert the battery (included in the product
package).
1. Open the battery cover by turning it
counterclockwise to OPEN using the sensor
fork or a coin (see picture 1).
2. Place the battery inside the cover with the
positive (+) side facing the cover (see
picture 2). Make sure the sealing ring is in
the groove to ensure water resistance.
3. Place the cover with the battery inside it
into the sensor.
4. Press the cover in place and close it by
turning clockwise from OPEN to CLOSE
using the sensor fork or a coin (see picture
3). The s3 stride sensor can be positioned
either on the shoelaces or in the sole cavity
of a specific running shoe.

Teach a New Stride Sensor to Your Wrist
Unit
Your new s3 stride sensor must be introduced to
your Polar product in order to analyze your
running technique and efficiency. This is called
teaching. For further information, refer to the
user manual or go to www.polar.fi/support.
Attach Stride Sensor on Shoelaces
1. Undo the flap and detach the fork (see
picture 4).
2. Loosen your shoelaces and place the fork
underneath them, on top of the tongue of
the shoe (see picture 5).
3. Tighten the laces.
4. Fit the front part of the sensor onto the fork
and press from the rear (see picture 6).
Fasten the flap.
5. Make sure the sensor does not move and is
aligned with your foot. The more secure the
sensor, the more accurately speed and
distance is measured.

ENGLISH
Calibrate the S3 Stride Sensor
Optional calibration of the stride sensor can
improve the accuracy of speed, pace and
distance measurements. It is recommended that
you calibrate the stride sensor before using it
for the first time, if there are significant
changes in your running style, or if the position
of the stride sensor on the shoe is dramatically
changed (e.g. if you have new shoes). You can
calibrate the stride sensor by running a known
distance, or by setting the calibration factor
manually.
Calibrate stride sensor during training
(on-the-fly calibration): You can calibrate the
stride sensor at any phase of your training
session with actual distance correction, when
you have run a known distance, preferably more
than 1000 meters, calibrate the stride sensor as
instructed in the user manual for the Polar
product in question.
Set calibration factor manually: The
calibration factor is calculated as a ratio of the
actual distance to the uncalibrated distance.
For instance if you run 1200 m and the Polar
product shows a distance of 1180 m, the
calibration factor is 1.000. Calculate the new
factor as follows: 1.000*1200/1180 = 1.017.
The measuring range for the factor is
0.500-1.500.

Service
During the two-year guarantee/warranty period,
we recommend that you service the product at
an authorized Polar Service Center only. The
warranty does not cover damage or
consequential damage caused by service not
authorized by Polar Electro.
Changing batteries: To change the batteries of
the stride sensor yourself, follow the given
instructions. To ensure the maximum lifespan of
the battery cover, open it only when changing
battery. When changing the battery, make sure
the sealing ring is not damaged. Battery kits
with sealing rings are available at well-equipped
Polar retailers and authorized Polar Service
Centers. In the USA and Canada, sealing rings
are available at authorized Polar Service Centers
only.
If you would prefer Polar to replace the battery,
contact an authorized Polar Service Center. The
Service will test the stride sensor after replacing
the battery.
Keep batteries away from children. If
swallowed, contact a doctor immediately.
Batteries should be properly disposed of
according to local regulations.

Care and Maintenance
Your safety is important to us. The shape of the stride
sensor is designed to minimize the possibility of getting
caught in something. In any case, be careful when
running with the stride sensor in brushwood, for
example.
The Polar S3 stride sensor is water resistant and can be
safely worn in the rain. Do not immerse the stride
sensor in water as it is not intended for underwater
activities. Do not expose to direct sunlight for extended
periods.
Keep your stride sensor in a cool and dry place. Do not
keep in a damp environment, in non-breathable
material (a plastic bag or a sports bag) nor with
conductive material (a wet towel).
