Thank you for viewing. The exterior color and buttons are black, making the overall appearance completely black. It exudes a very high-class atmosphere and sits majestically. The screen uses an IPS LCD with a backlight. It is integrated with a glass screen, and there is no gap between the screen and the LCD, so dust, etc., will not enter. Holding down Select enters the settings change mode. After that, pressing Select cycles through the items ("BRT", "CLR", "DSP", "FRM", "CG") in that order (see below), and you can change the settings by pressing the L button or the R button. When you have finished changing the settings, hold down Select again to exit the settings change mode. The settings are remembered even when the power is turned off. ※ About the settings items BRT (Brightness) .....
