(1) If the interruption time is shorter than the response time, the obstructing object is not detected.
(2) In areas where there are large objects fluttering in the wind and obstruct the optical axis (e.g., birds, newspaper, and
cardboard), set the response time slightly slower according to the installation condition. (However, if the response time
is too slow, the units may not detect an intruder.)
