This service manual is intended for qualified service technicians; it is not
meant for the casual do-it-yourselfer. Qualified technicians have the neces¬
sary 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.
WARNING
Lead in solder used in this product is listed by the California Health and Welfare agency as
a known reproductive toxicant which may cause birth defects or other reproductive harm
(California Health & Safety Code, Section 25249.5).
When servicing or handling circuit boards and other components which contain lead in in
solder, avoid unprotected skin contact with the solder. Also, when soldering do not inhale
any smoke or fumes produced.
1. SAFETY INFORMATION
-(FOR USA MODEL ONLY)-
1. SAFETY PRECAUTIONS
The following check should be performed for the
continued protection of the customer and service
technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known earth ground
(water pipe, conduit, etc.) by connecting a leakage
current tester such as Simpson Model 229-2 or
equivalent between the earth ground and all exposed
metal parts of the appliance (input/output terminals,
screwheads, metal overlays, control shaft, etc.). Plug
the AC line cord of the appliance directly into a 1 20V
AC 60Hz outlet and turn the AC power switch on. Any
current measured must not exceed 0.5mA.
ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A PO¬
TENTIAL SHOCK HAZARD AND MUST BE COR¬
RECTED BEFORE RETURNING THE APPLIANCE TO
THE CUSTOMER.
2. PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the appli-
ance'have special safety related characteristics. These
are often not evident from visual inspection nor the
protection afforded by them necessarily can be ob¬
tained by using replacement components rated for vol¬
tage, wattage, etc. Replacement parts which have
these special safety characteristics are identified in
this Service Manual.
Electrical components having such features are
identified by marking with a A on the schematics and
on the parts list in this Service Manual.
The use of a substitute replacement component which
dose 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 information, always consult the current
PIONEER Service Manual. A subscription to, or ad¬
ditional copies of, PIONEER Service Manual may be
obtained at a nominal charge from PIONEER.
