Place a container front of the fiber optic sensor lead.
Follow the fiber optic sensor lead back to the amplifier. Then press and hold the "Autoset" button for 3 seconds until the sensor blinks.
Release the "Autoset" button. Then sensor will flash and both the green and red LEDs will remain illuminated.
Pass the container in front of the fiber lead to ensure the sensor is detecting the container properly. When a container is present the green and red LEDs will be illuminated.
