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.
÷ 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 × 101= 561 ................................................... RD1/4PU 5 6 1 J
47k
= 47 × 10 3 = 473 .................................................. RD1/4PU 4 7 3 J
0.5
= R50 ...................................................................... RN2H Â 5 0 K
1
= 1R0 ......................................................................... RS1P 1 Â 0 K
Ex. 2
When there are 3 effective digits (such as in high precision metal film resistors).
5.62k
= 562 × 10 1 = 5621 ........................................... RN1/4PC 5 6 2 1 F
÷ Parts marked by
are important parts which relate in X-rays radiation.
If any of these parts need to be replaced, always replace with specified parts.
÷ Parts marked by × are important parts which relate in X-rays radiation. If a failure occurs in any of these parts, replace the
printed circuit board assembly where the relevant part has already been adjusted as a working component. Do not replace the
actual part itself. If any part marked by
× is replaced, there is danger of being exposed to X-rays.
÷ Reference Nos. indicate the pages and Nos. in the service manual for the base model.
