Pair Kéo Power with V800

Before pairing Kéo Power make sure you have installed the it correctly. For information on mounting the pedals and installing the transmitters see the Polar LOOK Kéo Power user manual that came in the product box or the video tutorial.


Both transmitters need to be paired one at a time, therefore you have to perform the pairing twice when taking Kéo Power into use. After pairing the first transmitter, you can immediately pair the second one by selecting it from the list. Check the device ID can found on the backside of each transmitter to make sure both transmitters have been paired.

There are two ways to pair Keó Power with your V800:

  1. Press START in time view to enter pre-training mode.
  2. Rotate the cranks to wake up the transmitters.
  3. The device ID Pair Polar PWR xxxxxxxx is displayed. Choose Yes.
  4. Pairing completed is shown when you are done.


  1. Go to General Settings > Pair and sync > Pair other device and press START.
  2. Rotate the cranks to wake up the transmitters. V800 starts searching for Kéo Power.
  3. Once the it is found, Polar PWR xxxxxxxx is displayed.
  4. Press START, Pairing is displayed.
  5. Pairing completed is displayed when you are done.

  • Set FTP value: Set your FTP value. The setting range is 60 to 600 watts.

Calibrate Kéo Power

Calibrate Kéo Power before starting your session. V800 calibrates itself automatically each time the transmitters wake up and V800 is found. The calibration takes a couple of seconds.

Training temperature has an effect on the calibration accuracy, so make sure your bike’s temperature has become stable before you start the offset calibration.

To calibrate Kéo power:

  1. Wake up the transmitters by rotating the cranks and choose pre-training mode on your V800 to start the calibration.
  2. Keep the bike upright and cranks in place until calibration is completed.

To ensure the calibration is done properly:

  • Do not put any weight on the pedals during calibration.
  • Do not interrupt the calibration.

When the calibration is complete a green LED will blink on the transmitters, and you can start your session.
