)
OF THE MECHANISM
POINTS TO NOTE
• Referring to “3. HOW TO REMOVE THE CABINET PARTS”
in the Service Manual, remove the cabinet parts and the
circuit board assembly, and remove the Compl Mechanism.
• The codes (letter and numbers in parentheses) indicate Loc.
No. in the parts list.
• When fitting the parts of the mechanism, refer to the “Assembly Notes”, and proceed in the reverse of the dis-assembly
order.
• Clamps and dowels are used to prevent parts coming loose.
When removing a clamp or dowel, be careful not to force it,
as this can result in damage.
• Since the dimension of the screw names in the figures are
subject to change without notice, always refer to the parts
list.
