Embarassing, but I can't set the date-time!
I go through the procedure using the rocker button, left-right, and up-down to change the numbers. Then when I have it correct, i press it centrally down. I think this should save the settings, but instead it moves to the next number to the right. Then if I exit, the date and time is all zeros. I used the ssame procedure to set the language and it worked fine. What am I dcoing wrong with such a basic operation?
