Switching the display’s brightness
The brightness of the display can be adjusted to one of four levels.
The DIMMER button also controls the Denon's Super Audio CD Player DCD-1600NE, so the DCD-1600NE can be operated simultaneously with this unit. When the two units have different settings, press and hold in the button for lease 2 seconds to reset them both to the default setting, then make the desired setting.
The display brightness is set to most brightly by default.
