Hi! If it still matters for someone, I also can access preset numbers over 1000. But i never tried to save there something. Version number 4.10. and an older unit with the v4.01. The cards were initially not readable, but I discovered a brutal method to formate them. You insert a card into the slot, but w/o contacting the pins. Then you press „format“ and push the card into the slot immidiately. It worked with three different cards sofar. But you have to be quick.
