I posted this item. The camera is working properly.I made a couple of mistakes. (1) shooting in nef I read the space left as the number of frames. This is not true. (2) The setting 12 HR 4 intervals 6 times results in 24 shots. True. The last parameter 6 times is the number of burst exposures not the sub intervals. So I got 6 exposures at each of the 4 hours. The fact that "active" is not flashing while the screen is blank is irrelevant. This was a good though time wasting experience.
