Operation
This function decreases noise at night or other times as necessary.
The input signal is recognized during its rising/falling phase.
(After reaching the top/bottom of the rising/falling edge, the signal must remain there for at least 100 ms.)
The system's capacity is reduced during low-noise operation.
The table below provides a rough guide to this capacity reduction.
* Position of noise measuring device: 1 m from the front face of the set and 1.5 m above ground (
