Nike + iPod: How to recalibrate if you get unexpected results

When you calibrate Nike + iPod, make sure you are running or walking at a steady, natural pace for the specified calibration distance. If you run or walk with an inconsistent pace or travel a distance that is over or under the expected calibration distance, you may get unexpected results (such as incorrect distance of a workout). For best results, first reset the calibration and then recalibrate, instead of just calibrating again.

Follow these steps to reset the calibration and recalibrate.

1. Connect the Nike + iPod receiver to iPod nano, and wear the Nike+ shoes with the sensor properly inserted. Walk around to activate the sensor.
2. On the iPod nano, navigate to Nike+iPod > Settings > Sensor > Calibrate.
3. Select the incorrect calibration setting and press the Center button.
4. Select "Reset to Default", and then press the Center button to confirm the reset.
5. Go to Nike+iPod > Settings > Sensor > Calibrate and calibrate again with a known distance.
