Switching the display’s brightness
Switching the display off reduces a source of noise that affects sound quality, enabling higher sound quality playback.
Press DIMMER.
The brightness of the display switches each time the button is pressed (4 levels).
When the display is turned off, the “DISPLAY OFF” indicator lights up on the display.
If you operate the buttons when the display brightness is set to “Off”, the display temporarily lights at 100% brightness level.
