INTRODUCTION
Polar Stride Sensor Bluetooth® Smart is the best choice for improving your running technique and efficiency. Usingsensitive inertial sensors, it gives accurate and highly responsive speed, distance, leg cadence and stride length
measurements.
Polar Stride Sensor Bluetooth® Smart is compatible with Bluetooth® Smart Ready devices that support Bluetooth®
Running Speed and Cadence Service.
You can use your sensor with dozens of leading fitness apps as well as with Polar products using Bluetooth® Smart.
Check the compatible products at support.polar.com.

GET STARTEDSTRIDE SENSOR BATTERYREMOVING THE BATTERY INSULATOR
Remove the battery insulator from the battery compartment before first use.
1. Open the battery cover by turning it counterclockwise using a coin.
2. Remove the red plastic insulator from the battery compartment.
3. Press the cover into place and close it by turning it clockwise.

CHANGING THE BATTERY
1. Open the battery cover by turning it counterclockwise to OPEN using a coin (picture 1).
2. Place the battery inside the cover with the positive (+) side facing the cover (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 a coin (picture 3).

To increase battery life, Polar Stride Sensor Bluetooth® Smart has three different power modes:
Measuring, Stand By and Deep Sleep mode. In Stand By mode, the sensor is visible to the receiving device
and a connection is possible. When connected to the receiving device, the sensor goes to Measuringmode. When disconnected, the sensor returns to Stand By mode. If the sensor is not touched during thenext couple of minutes, it goes to Deep Sleep mode. The slightest movement will make the sensor returnto Stand By mode.

PAIRING AND CALIBRATING THE STRIDE SENSORPAIR THE STRIDE SENSOR WITH YOUR RECEIVING DEVICE
Polar Stride Sensor Bluetooth® Smart must be paired with the receiving device in order to analyze your runningtechnique and efficiency. For more information, see the user guidance material of the receiving device or mobileapplication.

CALIBRATE THE STRIDE SENSOR
Calibration of the stride sensor improves the accuracy of speed, pace, distance and stride length measurements. It is
recommended that you calibrate the stride sensor before using it for the first time, if there are significant changes inyour running style, or if the position of the stride sensor on the shoe is dramatically changed (e.g. if you have newshoes or if you switch the sensor from your right shoe to your left one). The calibration should be done at the speed
you normally run.
Calibration is done via the receiving device. See the user guidance material of the receiving device or mobile
application for instructions.

ATTACHING THE STRIDE SENSOR
Attach the stride sensor on shoelaces:
1. Undo your shoelaces and place the holder on top of the tongue of the shoe. Make sure the holder flap is facingupwards.
2. Thread the laces in through the holes on the sides of the holder and out through the hole on the bottom of theholder (pictures 1 and 2). Thread the laces through the small flap on the tongue of the shoe to ensure theholder does not move while running.
3. Tighten the laces.
4. Fit the front part of the sensor into the holder and press from the rear (picture 3). Fasten the flap.
5. Make sure the sensor does not move and is aligned with your foot. The more secure the sensor, the moreaccurately speed and distance is measured.

IMPORTANT INFORMATIONSERVICE
During the two-year guarantee/warranty period we recommend that you have service, other than battery
replacement, done by an authorized Polar Service Center only. The warranty does not cover damage or consequential
damage caused by service not authorized by Polar Electro. For contact information and all Polar Service Center
addresses, visit www.polar.com/support and country-specific websites.
Changing batteries: To change the batteries of the stride sensor yourself, follow the given instructions. To ensure themaximum lifespan of the battery cover, open it only when changing the battery. When changing the battery, makesure the sealing ring is not damaged, in which case you should replace it with a new one. You can purchase the sealing
ring/battery kits at well-equipped Polar retailers and authorized Polar Services. In the USA and Canada, the additional
sealing rings are available at authorized Polar Service Centers. In the USA, the sealing ring/battery kits are alsoavailable at www.shoppolar.com. Go to www.polar.com to find your own country's shoppolar online store.
The battery level of your stride sensor is displayed on the receiving device if it supports Bluetooth® Battery Service.

CAUTION:
Risk of explosion if battery is replaced by an incorrect type. Dispose of batteries according to the instructions.
Keep batteries away from children. If swallowed, contact a doctor immediately. Batteries should be properly disposedof 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 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 (aplastic bag or a sports bag) nor with conductive material (a wet towel).
