- When ordering service parts, be sure to refer to "EXPLODED VIEWS and PARTS LIST" or "PCB PARTS LIST".
The > mark found on some component parts indicates the importance of the safety factor of the part.
-
Therefore, when replacing, be sure to use parts of identical designation.
- : The power supply is shown with the marked box.
