SAFETY INFORMATION
A
This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual. Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty. If you are not qualified to perform the repair of this product properly and safely, you should not risk trying to do so and refer the repair to a qualified service technician.
B
WARNING This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to cause cancer, birth defects or other reproductive harm. Health & Safety Code Section 25249.6 Proposition 65
NOTICE (FOR CANADIAN MODEL ONLY) Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement parts must be of identical designation. REMARQUE (POUR MODÈLE CANADIEN SEULEMENT)
C
Les symboles de fusible
(fusible de type rapide) et/ou
(fusible de type lent) sur CCI indiquent que
les pièces de remplacement doivent avoir la même désignation.
(FOR USA MODEL ONLY) 1. SAFETY PRECAUTIONS
The following check should be perfor med for the continued protection of the customer and ser vice technician.
LEAKAGE CURRENT CHECK
D
Measure leakage current to a known ear th ground (water pipe, conduit, etc.) by connecting a leakage current tester such as Simpson Model 229-2 or equivalent between the ear th ground and all exposed metal par ts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60 Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5 mA.
ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER. 2. PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the appliance have special safety related character istics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, wattage, etc. Replacement par ts which have these special safety character istics are identified in this Service Manual. Electr ical components having such features are identified by marking with a on the schematics and on the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards. Product Safety is continuously under review and new instructions are issued from time to time. For the latest infor mation, always consult the current PIONEER Service Manual. A subscription to, or additional copies of, PIONEER Ser vice Manual may be obtained at a nominal charge from PIONEER.

5. PCB PARTS LIST
NOTES: Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. 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. 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 56 x 10 1 RD1/4PU 5 6 1 J 561 47k RD1/4PU 4 7 3 J 47 x 10 3 473 0.5 RN2H R 5 0 K R50 1 RS1P 1 R 0 K 1R0 Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k 562 x 10 1 5621 RN1/4PC 5 6 2 1 F
