1. SAFETY INFORMATION
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.
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
1. SAFETY PRECAUTIONS
The following check should be performed for the
continued protection of the customer and service
technician.
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
voltage, 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
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 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.
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 120V
AC 60 Hz outlet and turn the AC power switch on. Any
current measured must not exceed 3.5 mA.
(FOR USA MODEL ONLY)
Also test with plug
reversed
(Using AC adapter
plug as required)

REMARQUE
(POUR MODÈLE CANADIEN SEULEMENT)
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.
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.
