How to adjust the LCD screen (Methods of turning ON or OFF the back light, and adjusting the contrast of the display screen)

1. Turning ON or OFF the back light

The back light is turned ON or OFF each time you press the panel switch [LIGHT]. Immediately after the power is turned ON, back light is always in OFF state regardless of enable or disable of the panel condition memory function.





2. Adjusting the contrast of the display screen

The contrast of the display screen is freely adjustable. Using the supplied adjustment screw driver, the LCD contrast volume at the bottom can be adjusted. Turning the volume clockwise increases the contrast, and turning it counterclockwise decreases the contrast. Also, by the automatic contrast correction function, setting contrast is kept in fixed concentration regardless of variation of ambient temperature.



Please do not turn the volume forcibly or push it strongly. It may cause a failure.
