5. PCB PARTS LIST
NOTES: Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. mark found on some component parts indicates the importance of the safety factor of the part. The Therefore, when replacing, be sure to use parts of identical designation. 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 = = 561... RD1/4PU 1 J 47k = = 473... RD1/4PU 3 J 0.5 = R50... RN2H K 1 = 1R0... RS1P K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k = = 5621.. RN1/4PC F

7.2 DIAGNOSIS

How to Diagnose the P-PACK (IC301, IC302 AND IC303) (At Bottom Side)
Cut six portions on the Under Base by nipper and remove a Cover. Front

Turn the Cover.

Diagnose the P-PACK (IC301, IC302 and IC303). Front
Fix the Cover with the three screws (BBZ30P080FMC) and stick the UL Caution Card (AAX-313).

AAX - 313

CAUTION : After performing the above operation, be sure to stick the UL caution card(Part No. : AAX-313) to the prescribed position. (It is required by the UL regulations.)
