If your sensor is already taught, select STOP.
If your sensor has not been taught, see Using a New Accessory (page 26) for more information on
teaching.
If you use the Polar Power Output Sensor™ W.I.N.D., follow the instructions below:
1. C. weight: Set chain weight in grams. Accept the set value with OK.
2. C. length: Set chain length in millimeters. Accept the set value with OK.
3. S. length: Set span length in millimeters. Accept the set value with OK.

For precise readings, all settings must be as accurate as possible. Chain length and weight are directly
proportionate to power value. If there is 1% error, the power value will also have 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.

Altitude Settings
Calibrate the altimeter to ensure accurate measurement.
Manual calibration: Set the reference altitude whenever a reliable reference, such as a peak or a
topographic map, is available or you are at the sea level.
Automatic calibration: By using the automatic altitude calibration, you can adjust the starting elevation to
be always the same in the beginning of the training session. Calibrate the elevation manually and turn the
automatic calibration on. From now on, this elevation will be always used as the base elevation in the
beginning of the training session if automatic altitude calibration is in use. Also, if the automatic
calibration is turned on and you calibrate the cycling computer manually, the new value will be used as a
new starting elevation for automatic calibration.
Select automatic calibration if you always train in the same environment to ensure correct altitude values.
