Before taking a new sensor into use, it has to be introduced to the training computer. This is called pairing and only takes a few seconds. Pairing ensures that your training computer receives signals from your sensor only, and enables disturbance-free training in a group.
Before entering an event or race, make sure that you do the pairing at home. This is to prevent interference due to the long-range data transmission. When pairing new sensor make sure you are not near (40 m/131 ft) other similar sensors.
↑ Back to topIf you have not paired your training computer with a heart rate sensor before, pairing is performed automatically when you start a training session. Wear the training computer and the heart rate sensor and start by pressing . Searching for new heart rate sensor is displayed. The training computer searches for a heart rate sensor signal. Heart rate sensor found is displayed when the the training computer finds the signal.
Wear the heart rate sensor and make sure that you are not near (40 m/131 ft) other heart rate sensors.
Go to Menu > Settings > Sport profiles > Sport > Heart rate sensor > Search new and press .

Only one heart rate sensor can be paired with your training computer at a time. However, the training computer remembers the last three pairings. If the most recently paired heart rate sensor is not available, but the previous is, the training computer receives the heart rate signal from the previous sensor.

You can have two bikes on the training computer. Each bike has to have the sensors separately taught. You can only teach one speed sensor to one bike. If you have two bikes, both of them can use the same speed sensor. Or, they can have their own set of sensors. When you pair a new sensor to a bike that already has a previously taught sensor in the memory, the new sensor replaces the previous one.
Go to MENU > Settings > Sport profiles > Cycling (Bike 1)/Cycling (Bike 2) > Bike 1 settings/Bike 2 settings > Speed sensor > Search new and press .

Make sure the stride sensor has been correctly attached to your shoe. For more information on setting up the stride sensor refer to the user manual of the stride sensor or to the video tutorial at http://www.polar.com/en/polar_community/videos.
You can only pair one stride sensor to the training computer at a time. If you pair a new sensor, the new sensor always replaces the previous one you had paired. The stride sensor can only be paired to the Running sport profile.
Go to MENU > Settings > Sport profiles > Running > Stride sensor > Search new and press .
Searching for new stride sensor is displayed. The training computer starts searching for the stride sensor signal.
Once the new stride sensor is identified, Stride sensor found is displayed. Pairing is complete.

Polar s3+ stride sensor can be set on only for the Running sport profile.
Calibration of the stride sensor improves 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 or if you switch the sensor from your right shoe to your left one). You can calibrate the stride sensor by running a known accurate distance, or by setting the calibration factor manually. The calibration should be done at the speed you normally run. If you run at different speeds, the calibration should be done at your average speed.
Before calibration the stride sensor needs to be paired with the training computer. For more information on pairing the stride sensor and training computer, see 10. New Accessory.
Make sure the stride sensor function in the training computer is on. Press to enter MENU and select Settings > Sport profiles > Running> Stride sensor > On.
To calibrate a certain distance with a step-by-step guidance, select
MENU > Settings > Sport profiles > Running > Stride sensor calibration > By running. Set distance is displayed.
Adjust the distance, how far you wish to run, to calibrate the stride sensor (minimum calibration distance is 400 meters / 0.3 miles). Press . Stand still until stride sensor is found is displayed.
Press OK (START) and run xx.x km/mi is displayed. On the starting line, press and start your run by taking the first step with your sensor foot and run the preset distance at a steady pace.
Press OK (START) after xx.x km/mi is displayed. Stop exactly on the finish line of the preset distance, stand still and press .
Once you reach the preset distance, stop exactly on the finish line of the preset distance and stand still for calibration. If you move before Calibrated to x.xxx is displayed, the calibration fails.
When the calibration succeeds, Calibrated to x.xxx is displayed. The new calibration factor is used. Continue recording? is displayed. If you wish to continue the training session recording, select Yes. Otherwise, select No.
To cancel the calibration press , Calibration canceled is displayed.
The calibration factor is calculated as a ratio of the actual distance to the uncalibrated distance. Example: you run 1200m, and the training computer shows a distance of 1180m, the calibration factor is 1.000. Calculate the new calibration factor as follows: 1.000*1200/1180 = 1.017. The range of the calibration factor during manual calibration is 0.500-1.500. If you define the calibration factor below or above these values, calibration fails.
To calibrate the stride sensor manually before training, select
Settings > Sport profiles > Running> Stride sensor > Set factor.
Adjust the factor. Calibareted to x.xx is displayed.
The calibration factor can also be set during training, when the stride sensor is in use. Press and hold to enter the Quick menu and then select Calibrate stride sensor > Set factor . Calibareted to x.xx is displayed and you can continue running.
Before calibration the stride sensor needs to be paired with the training computer. For more information on pairing the stride sensor and training computer, see 10. New Accessory.
Set correct lap distance
You can calibrate the sensor at any phase of your training with lap distance correction, provided you are not training with distance-based targets. Just run a known distance, preferably more than 1000 meters / 0,62 miles.
Make sure the stride sensor function in the training computer is on. In time mode press to enter MENU and select Settings > Sport profiles > Running> Stride sensor > On.
In time mode press and select Running as your sport profile. Press again and start running.
At the starting point of a known lap distance, press (minimum calibration distance is 400 meters / 0.3 miles). When you have run the whole lap distance, press .
Then calibrate the sensor: Press and hold to go enter Quick menu. Select Calibrate stride sensor.
Select Set correct lap distance. Fix the displayed lap distance with the distance you just ran, and press . Calibrated to x.xxx is displayed. The sensor is now calibrated and ready for action.
Set correct distance
Alternatively, you can calibrate the stride sensor by fixing the whole distance gathered.
In time mode press and select Running as your sport profile. Press again and start running.
Press and hold to enter the Quick menu. Select Calibrate stride sensor.
Select Set correct distance. Fix the displayed distance with the distance you just ran, and press . Calibrated to x.xxx is displayed. The sensor is now calibrated and ready for action.
