Mark Symbol and Description
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.
÷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 Ω=56 ×101 =561................................................... RD1/4PU 561J
47k Ω=47 ×10 3=473 .................................................. RD1/4PU 473J
0.5 Ω=R50 ...................................................................... RN2H Â50K
1 Ω=1R0 ......................................................................... RS1P 1Â0K
Ex. 2 When there are 3 effective digits (such as in high precision metal film resistors).
5.62k Ω=562 ×10 1=5621 ........................................... RN1/4PC 5621F
