NOTES:
·Parts marked by "NSP" and
can not be supplied.
·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.
· Screws adjacent to mark on the product are used for disassembly.
·Reference Nos. indicate the pages and Nos. in the service manual for the base model.
·When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).
