5-2 Order of Disassembly

1) Refer to the disassembly fl owchart in Figs. 5-2-1 for the order of removing each component.
Unless otherwise specifi ed, use the reverse procedure to reassemble the removed components.
2) When replacing the MAN circuit board, it is recommended that you back up the EEPROM data
in advance, referring to "5-4 EEPROM data backup and write"; write the EEPROM data after
replacing the MAN circuit board.
3) After replacing any circuit boards and any units, perform any necessary adjustments according to
"6-3-2 List of adjustments needed after replacing major components".
Note:
When replacing components, be sure to use only those shown in "Replacement Parts List".
Reading Disassembly Flowchart:
After locating the target component in the fl owchart, remove all components in sequence until the
target is reached, following the arrows (routes) from the top left of fl owchart. If multiple routes exist
to the target component from the top of fl owchart, remove all the components on all the routes.
