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
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
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 120V
AC 60Hz outlet and turn the AC power switch on. Any
current measured must not exceed 0.5mA.
Reading should
not be above
0.5mA
Test all
exposed metal
surfaces
. . .n
. . Also test with
'-''''
reversed
Jplug
(Using AC adapter
plug as required/
AC Leakage Test
2
Earth
ground
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 characteristics. 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 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
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 additional copies of, PIONEER Service Manual may be
obtained at a nominal charge from PIONEER.

8. CIRCUIT DESCRIPTION
• S-MPX circuit
The S-MPX is a circuit for eliminating the ultra-close
interference that cannot be removed with the standard MPX
demodulator. It can minimize the beat noise caused by
adjacent stations (100kHz to 200kHz) with FM stereo
reception.

Interferenoe(noise)
Interference

Because the standard type MPX has a demodulation band up
to 53 KHz, it is affected by interferences. However, the SMPX (Single Side-band MPX) has a demodulation band up
to 38 KHz and is thus not affected by interferences.

CONNECTING THE POWER CORD
(For U.S. and Canadian models)
°Power cord
Household electrical outlets are provided with specific polarity, a
live side and a neutral (ground) side. This unit utilizes such polarity
in order to improve sound quality. As shown in the illustration, be
sure to insert the power plug so that its blades match the width of
slots in the outlet.
POWER-CORD CAUTION
Household electrical outlet.
Long slot is neutral
(ground) side.
Handle the power cord by the plug. Do not pull out the plug by tugging
the cord and never touch the power cord when your hands are wet as
this could causes Short circuit or electric shock, Do not place the unit,
a piece of furniture, etc,. on die power cord, or pinch the cord. Never
make a knot in the cord or tie it with other cords. The power cords
should be routed such that they are not likely to be stepped on. A
damaged power cord can cause fire or give you an electrical shock.
Check the power cord once in a while. When you find it damaged, ask
your nearest PIONEER authorized service center or your dealer for a
replacement.
Insert the wide blade
into the ground side slot.
