NOTES: OParts marked by "NSF" are generally unavailable because they are not in our Master Spare Parts List.
I The /I\ markfound 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.
0 Screws adjacent to Y mark on product are used for disassembly.
lReference Nos. indicate the pages and Nos. in the service manual for the base model.
I When ordering resistors, first convert resistance values into codeform as shown in thefollowing examples.
Ex! When there are 2 effective digits (any digit apartfrom 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).

560 - 56 X 10 - 561 ------------------------------
47k a 47 X 10 a 473
0.5 - R50 --
1 - 1R0 - RSIP-EflK
EX.2 When there are 3 eflective digits (such as in high precision metalfilm resistors).
