Swivel the sensor head in the direction you wish to cover.
Set the range switch on the bottom of the sensor to "Max" to cover the entire area in front of the sensor.
Set the time delay to the lowest setting using a flat head screwdriver.
Set the control for light of day to the daylight setting.
Walk in front of the sensor in different areas to test the light's sensitivity.
Adjust the time delay and the sensitivity in small increments, walking by the sensor each time to turn the light on. Turn the range control towards minimum to shorten the range of the sensor. Adjust the time delay to alter how long it takes the light to turn on when it detects movement.
