CHANGE OF OPTICAL PICK-UP BLOCK
KSM-213CAM n KSM-213CDM
Since the new chassis assy (MB) (RP), motor (including M702) and chucking plate are not compatible with the former ones, when
replacing either of these parts, replace them with the same version.
How to distinguish the sets
You can distinguish the sets by the optical pick-up type name printed on the optical pick-up block.
