Calibration manually

Adjust the SET factor to the value 1000 before manual calibration.

The calibration factor is calculated as a ratio of the actual distance to the uncalibrated distance. For example if you ran 1200 meters and the wrist unit shows a distance of 1180 meters, the calibration factor should be adjusted to 1200/1180 x 1000 = 1017.

If you start from the Time of Day display, repeat steps 1-5.

You can set two bike preferences for the wrist unit. Make the settings ready for both bikes; when you start exercising, just select bike 1 or 2. As you take the bike settings 1 or 2 in use speed and distance measuring functions are always on. Select the bike features off when exercising without a bicycle. Wheel size settings are a prerequisite for cycling information.
