CONTRAST OF MISCELLANEOUS PARTS 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. NOTES: 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%). Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5 6 1 4 7 3 R 5 0 1 R 0 5 6 2 1 560 47k 0.5 1 RD1/4PU J RD1/4PU J RN2H K RS1P K 56 x 101 47 x 103 R50 1R0 561 473 5.62k RN1/4PC F 562 x 101 5621 CONTRAST TABLE Part No. Ref.
