To increase the switching distance: Turn potentiometer
clockwise.
To reduce switching distance: Turn potentiometer
counter-clockwise.
1. Position the sensor at the desired distance to the
object.
2. Set the potentiometer so that the object is reliably
detected: The yellow LED will be on toindicate light is
being received.
3. Remove the object. The background should not be
detected: The yellow LED should not be on.
