Contrast Adjustment Mode
The LCD contrast can be adjusted by entering the Contrast Adjustment Mode. This mode is
entered by double pressing the button on the front panel.
Once in Contrast Adjustment Mode, pressing the button will lighten the contrast and decrease
the contrast by one level. There are five different contrast levels and the LCD will cycle from the
lightest to darkest if the button is pressed when on the lightest setting.
To exit the Contrast Adjustment Mode, simply double-press the button on the front panel
again. The button will return to normal operation after this.
