A new sensor purchased as a separate accessory has to be introduced to the cycling computer. This is called teaching and takes only a few seconds. Teaching ensures that your cycling computer receives signals from your sensor only, enabling disturbance-free exercise in a group. If you have purchased the sensor and the cycling computer as a set, the sensor has already been “taught” to work together with the cycling computer. You just need to activate the sensor in your cycling computer.
You can teach one speed, cadence and power sensor for each bike setting.
Select Settings > Bike SET > Bike 1/ 2 / 3 > Speed SET > ON. Speed TEACH? is displayed
To teach a new sensor, make sure you are not near (40 m/131 ft) other speed sensors. To confirm teaching, press Test drive is displayed. To activate the sensor, press and rotate the wheel a few times. A flashing red light indicates that the sensor is activated. Completed! is displayed once the teaching process is over. The cycling computer is now ready to receive speed and distance data.
.If Teaching FAILED is displayed, the cycling computer may be detecting the signal of more than one sensor or the sensor is not activated. Make sure you are not near (40 m/131 ft) other speed sensors and press . Try again? is displayed. Press and rotate the wheel a few times to activate the sensor.
If you want to cancel teaching, press STOP. The already taught speed sensor is taken into use.
Select Settings > Bike SET > Bike 1/ 2 / 3 > Cadence SET > ON. Cadence TEACH? is displayed
To teach a new sensor, make sure you are not near (40 m/131 ft) other cadence sensors. To confirm teaching, press Test drive is displayed. To activate the sensor, press and rotate the crank a few times. A flashing red light indicates that the sensor is activated. Completed! is displayed once the teaching process is over. The cycling computer is now ready to receive cadence data.
.If Teaching FAILED is displayed, the cycling computer may be detecting the signal of more than one sensor or the sensor is not activated. Make sure you are not near (40 m/131 ft) other cadence sensors and press . Try again? is displayed. Press and rotate the crank a few times to activate the sensor.
If you want to cancel teaching, press STOP. The already taught cadence sensor is taken into use.
Select Settings > Bike SET > Bike 1/ 2 / 3 > Power SET > ON.

Examples of chain weights and lengths (Due to the variation of the measurements, Polar cannot be held responsible for their validity):
Weight

Shimano Dura-Ace CN-7700 Super narrow HG

Shimano Sora CN-HG50

Campagnolo Record 2000, 10 Speed Chain

Campagnolo 10 Speed Chains Chorus, Centaur

Campagnolo Veloce, Mirage, and Xenon

For precise readings, all settings must be as accurate as possible. Chain length and weight are directly proportionate to power value. If they have, for example, 1% error, then the Power Value will also have this 1% error.
There is no need to re-enter chain length and weight if links are removed. The system uses chain density (weight/length). Removing links from the chain does not affect density.
Power TEACH?:
To teach a new sensor, make sure you are not near (40 m/131 ft) other power sensors. To confirm teaching, press Test drive is displayed. To activate the sensor, press and rotate the crank a few times. A flashing red light indicates that the sensor is activated. Completed! is displayed once the teaching process is over. The cycling computer is now ready to receive power data.
.If Teaching FAILED is displayed, the cycling computer may be detecting the signal of more than one sensor or the sensor is not activated. Make sure you are not near (40 m/131 ft) other power sensors and press . Try again? is displayed. Press and rotate the crank a few times to activate the sensor.
If you want to cancel teaching, press STOP. The already taught power sensor is taken into use.
*Optional sensor required.
