I've figured out about everything, focus priority, bracketing, long exposures, but NOT the intervals and multiple exposure which are related somehow to 'start time'. Several screens can be set for that first function: One starts _F __ which must have a number 1-99 placed in both spots. Could the first be how many frames and the second how many exposures per frame. Another screen is __:__ __ and must be at least 00:00 01 to for things to work. Could be HH:MM SS - Is that an interval between shots? Another begins as __ but sets to DD HH:MM which results in an exposure being made that that precise time. (got start time nailed) I've given up finding a manual. The last one advertised on the web evaporated.
