and also a CESD on how to hard reset sig3.
same method, but the switch is even harder to find..
well actually i didn't try to hard reset my MP780 now, but i think i see the switch
(i just removed the battery to check it
). it should be somewhere in the middle, in the big recess, and the switch is the left of it. sorry if i'm mistaken, i don't want to test it right now
all of this is based on my experience with sig3.
