Note 2:
When the MS-476 board is defective, exchange
the entire CDM90 ASSY.
Note 3:
When the MOTHERBOARD mounted pc board
is replaced, be sure to refer to “DESTINATION
SETTING METHOD” on page 5.
Note 1:
W h e n t h e M O T H E R B O A R D b o a r d i s
replaced, spread the compound referring to
“NOTE OF REPLACING THE IC2002 ON
THE MOTHERBOARD BOARD AND THE
MOTHERBOARD MOUNTED PC BOARD” on
servicing notes (page 6).
Note:
The components identified by mark
0
or
dotted line with mark
0
are critical for safety.
Replace only with part number specified.
