Note 1:
Among mounted electrical parts on each boards, only
parts that are described in the electrical parts list can
be replaced for repair.
The parts that are not described in the electrical parts
list cannot be replaced with single for repairing.
Note 2:
When the complete AMP board is replaced, refer to
“SPREADING OF COMPOUND” on page 8.
