SX-255R, SX-2O5 10. FOR SX-255R/KCXJ, YPWXJ, SX-205/KUXJ AND SDXJ NOTES • • Parts marked by " NSP " are generally unavailable because they are not in our Master Spare Parts List. • The A markfound on some component parts indicates the importance of the safetyfactor of the part. Therefore, when replacing, be sure to use parts of identical designation. • Parts marked by " 0" are not always kept in stock. Their delivery time may be longer than usual or they may be unavailable. • When ordering resistors, first convert resistance values into codeform as shown in thefollowing 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%). 560,0 -056 x I0'= 561 RD1/4PUDET:1,1 47k fl -047 x10 3 = 473 RDI/4PU EEL] J 0.512 -0 ORS RN2HI EEK 1,(2 -+1R0 RS1P K Ex. 2 When there are 3 effective digits (such as in high precision metalfilm resistors). 5.62k II -0- 562 x10 = 5621 RAT1/4PCOEMMF CONTRAST OF MISCELLANEOUS PARTS SX-255R/KCXJ, YPWXJ, SX-205/KUXJ, SDXJ and SX-255R/KUXJ have the same construction except for the following: Mark No. Symbol & Description NSP COMPLEX Assy 38 MOTHER Assy 39 FL AND UCOM Assy 43 VOL.
