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. 1When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown byJ = 5%, and K = 10%).560 = 56 10 1 = 561.
