Educating Your Stride SensorAbout the Stride SensorThis device contains a stride sensor that uses a stride algorithm to learn your pace from your actual speed and yourbody's vibration frequency. This allows the device to calculate distance and laps with high precision, as well as measureyour pitch and stride even in locations that cannot receive signals from GPS satellites such as in a tunnel, and so on(SF-710/SF-510 only).Educating the Stride SensorWhen using the device for the first time, run under the following conditions so that the stride sensor can learn yourstride.Location/TimeRun or walk in the following locations that allow GPS positioning.❏ When outside with no obstructions overhead: Approximately 10 mins.❏ When surrounded by tall buildings: approximately 30 mins.MeasureMeasure using the chronograph function.U “Measuring Time, Distance, and Speed (Chronograph Function)” on page 37Note:❏ You do not need to make these preparations from the second time. However, note that information on your stride isinitialized if the device is initialized. If this occurs, you need to educate the stride sensor again.❏ When you mainly use the device for walking, from the Mes. Settings menu, set Activity Type to Walk.U “Mes. Settings” on page 87❏ The device's stride sensor is used for running and walking. This does not support bike mode. In bike mode, "-" isdisplayed for the stride and pitch on the measurement display.❏ Large measurement errors may occur if your stride differs significantly from this learning session.SF-710/510/310 User's GuidePreparing and Basic Operations32
