2.3 DISASSEMBLY/ASSEMBLY OF MECHANISM AS-
SEMBLY

2.3.1 General statement

The mechanism should generally be disassembled/assem-
bled in the C.IN mode (ASSEMBLY mode). (Refer to Fig.
2-3-1,2.)
However, when the mechanism is removed from the main
body, it is set in the STOP mode. Therefore, after the
mechanism is removed from the main body, supply 3 V DC
to the electrode on the top of the loading motor to enter
the mechanism mode into the C,IN mode compulsory.

can be distinguished from others by the relative position
of " ", "Q", " " " " marks on the sub cam gear to the in-
Q
ner or outer protrusion on the main deck.
