Note: When the BT board is replaced, it is necessary to confirm

operation.
Refer to “BLUETOOTH FUNCTION CHECKING METHOD
USING A CELLULAR PHONE” of the servicing note (See
page 5).

•

Due to standardization, replacements in the
parts list may be different from the parts
specified in the diagrams or the components
used on the set.

•

-XX and -X mean standardized parts, so they
may have some difference from the original
one.

•

Items marked “*” are not stocked since they
are seldom required for routine service.
Some delay should be anticipated when
ordering these items.
