CONTRAST OF MISCELLANEOUS PARTSParts marked by NSP are generally unavailable because they are not in our Master Spare Parts List.The mark found on some component parts indicates the importance of the safety factor of the part.

4、Therefore, when replacing, be sure to use parts of identical designation.Screws adjacent to mark on product are used for disassembly.Reference Nos. indicate the pages and Nos. in the service manual for the base model. NOTES:When ordering resistors, first convert resistance values into code form as s
