ÖThe 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. ÖReference Nos. indicate the pages and Nos. in the service manual for the base model. ÖWhen 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 W = 56 ´ 10 1 = 561 ...................................................RD1/4PU 5 6 1 J 47k W = 47 ´ 10 3 = 473 ..................................................RD1/4PU 4 7 3 J 0.5 W = R50 ......................................................................RN2H å 5 0 K 1 W = 1R0 .........................................................................RS1P 1 å 0 K Ex. 2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k W = 562 ´ 10 1 = 5621...........................................RN1/4PC 5 6 2 1 F Note *: Refer to Ò 7 CONTRAST OF PCB ASSEMBLIES Ó and Ò 2.
