Display

This menu item allows you to adjust the appearance of the screen. Only one mode can be selected at a time.

If you select Auto mode, the screen will automatically adjust the display for day or night, depending upon the lighting conditions.

If you select Day mode, the screen will be in the mode best suited for daylight conditions. The displays on the screen are usually brighter with a lighter background so that you can see them better during the brighter daylight hours.

To select one of these modes, press the button to the right of the screen with the dot on it that corresponds to the prompt. An X will appear in the box next to it to show it has been selected.

You can select day or night mode regardless of the lighting conditions.

To adjust contrast or brightness press the multi-function button that corresponds to the prompt at the right of the screen. Brightness is only available when dimming is active. It is not available when Auto is selected and it is daytime or when Day is selected. Turn the TUNE/SEL knob to increase or decrease the contrast or brightness.
