Setting the night mode

When the volume is set to a low level, for example, at night, setting the
night mode to “ON” will make sounds at low-volume levels easy to hear.
If you do not want sudden and drastic sound level changes due to
explosive sounds etc., setting this mode to “ON” will reduce extreme
sound level changes.
Press the NIGHT button.
The FL display becomes dimmer than usual. “NIGHT ON” is shown on the
FL display and the “NIGHT” indication in red letters lights up.
To set the night mode to “OFF”, press the NIGHT button again.
