The sensitivity (sensing range) is adjusted by pressing the teach-in button. Do not
operate the teach-in button using sharp objects. Once the sensitivity is set, remove
the object from the beam path. The switching output changes (see Graphic C).
The sensor is adjusted and ready for operation. Refer to Graphics C and G to check
the function. If the switching output fails to behave in accordance with Graphic C,
check application conditions. See section Fault diagnosis.
