Low noise operation level via the external control adaptor.
If the system needs to be running under low noise operation
conditions when an external signal is sent to the unit, this setting
defines the level of low noise that will be applied.
This setting will only be effective when the optional external control
adaptor (DTA104A61/62) is installed and the setting [2‑12] was
activated.
