7. USING A NEW ACCESSORY

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.

Teaching a New Speed Sensor

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 OK. Test drive is displayed. To activate the sensor, press OK 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 OK. Try again? is displayed. Press OK 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.

Teaching a New Cadence Sensor*

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 OK. Test drive is displayed. To activate the sensor, press OK 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 OK. Try again? is displayed. Press OK 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.

Teaching a New Power Output Sensor*

Select Settings > Bike SET > Bike 1/ 2 / 3 > Power SET > ON.

  • C. length: Set chain length in millimeters. Accept the set value with OK.

  • C. weight: Set chain weight in grams. Accept the set value with OK.

  • S. length: Set span length in millimeters. Measure the distance from the centre of the rear hub to the centre of the bottom bracket as shown in the picture. Accept the set value with OK.

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

     

    Weight

    Length

    Shimano Dura-Ace CN-7700 Super narrow HG

    280 g

    1473 mm

    Shimano Dura-Ace CN-7701 Ultegra CN-HG92, 105 HG72,105 HG73

    280 g

    1473 mm

    Shimano Sora CN-HG50

    335 g

    1473 mm

    Campagnolo Record 2000, 10 Speed Chain

    260 g

    1473 mm

    Campagnolo 10 Speed Chains Chorus, Centaur

    274 g

    1473 mm

    Campagnolo Veloce, Mirage, and Xenon

    277g

    1473 mm

    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 OK. Test drive is displayed. To activate the sensor, press OK 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 OK. Try again? is displayed. Press OK 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.
