1. CONTRAST OF MISCELLANEOUS PARTS

NOTES: Parts 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. 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.

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%).
560		56 x 101		561	RD1/4PU 5	6	1 J
47k		47 x 103		473	RD1/4PU 4	7	3 J
0.5		R50			RN2H R 5 0 K
1		1R0			RS1P 1 R 0 K
Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).
5.62k		562 x 101		5621	RN1/4PC 5 6 2 1 F
