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
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. Aliso, when soldering do not inhale any smoke or fumes produced.
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 MODELE CANADIEN SEULEMENT)
Les symboles de fusible -@&— (fusible de type rapide) et/ou -§E—=% (fusible de type lent) sur CCI indiquent que les
piéces de replacement doivent avoir la méme désignation.
(FOR USA MODEL ONLY)

AC Leakage Test
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, shownin
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-
ditionai copies of, PIONEER Service Manual may be
obtained at a nominal charge from PIONEER.

NOTES:
*
Parts
marked
by
“NSP”
are
generally
unavailable
because
they
are
not
in
our
Master
Spare
Parts
List.
¢
The
A\
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.
PD-M602
¢
Parts
marked
by
“@”
are
not
always
kept
in
stock.
Their
delivery
time
may
be
longer
than
usual
or
they
may
be
unavailable.
¢
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%).

8. ADJUSTMENTS
8.1. Adjustment Methods
PD-M602
If a disc player is adjusted incorrectly or inadequately, it may malfunction or not work at all even though there is
nothing at all wrong with the pickup or the circuitry. Adjust correctly following the adjustment procedure.
@ Adjustment Items/Verification Items and Order
If the specified values cannot be obtained or no adjustment is possible by performing the verifications or adjustments
described in steps 1 — 4, the pickup block may be defective.
