When I want the display the 'date light' everything seems fine but when I select "Menu" it displays at the bottom, right the 'icon' moon with a diagonal line across it. I assume this means that it will always show in "daylight" mode only?
If I remove the diagonal line it immediate "night time" mode and will stay in there in bright, sunny days. I thought that this mode was automatic, "day time/night time"?
