Walk Test

Walk in front of the motion detector in both directions.  The LED should light for 2-3 seconds each time your motion is detected. (Keep in mind that the detector will sleep for 2 min after detecting motion in an effort to save battery life.)

Important! Walk test at least once a week to verify proper function of the detector.
