Adjusting the Contrast for the Display
Once power is applied to the system, the LCD should be active. Use the up arrow keys and down arrow keys (1) on the LCD in order to increase the contrast of the screen or decrease the contrast of the screen if "Menu" is not displayed in the LCD or there is no text that is visible.
Once the screen is adjusted for the best viewing, the adjustment is done. The current setting is saved in non-volatile memory. The non-volatile memory will remember the setting through the power cycles.
