How to calibrate altitude

The RS800 / RS800CX / CS500 / CS600 / CS600X measures and displays altitude. With calibration you ensure your Polar product has the correct reference altitude to base its measurement on. Check your altitude calibration whenever a reliable reference, such as a peak or a topographic map, is available, or when at sea level.

To calibrate altitude, go to SettingsFeaturesAltitudeCalibrate and enter the desired altitude value.
In CS500, go to SettingsAltitude SETCalibrate and enter the desired altitude value.

To set altitude function on or off in RS800 / RS800CX, go to SettingsFeaturesAltitudeOn / Off.


In CS500 / CS600 / CS600X the altitude measurement is always on.
