Hello to all who have managed to get to the new address so far. Somebody really put some thought into the subscription mode and alternatives. Anyway, I know from experience and literature that the R4, RE and R5 are supplied by the batteries in the winder/motor and that the R7 isn't, but I can't find any reference in my Leica library about the R3MOT. Is it also a "dual supply" configuration ? thanks Douglas
