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.
Also,
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 -E—B (fusible de type rapide) eVou -$E=8 (fusible de type lent) sur CCI indiquent que les
piaces de remplacement doivent avoir la méme désignation.
(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
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
Leakage | NOt be above
0.5mA
current

Device
under
test
Test all
exposed metal
surfaces
Also test with
plug reversed
(Using AC adapter
plug as required)
Earth
ground
AC Leakage Test
equivalent between the earth ground and all exposed.
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.

Additional Laser Caution
1. Laser Interlock Mechanism
The position of the switch (S601) for detecting loading
completion is detected by the system microprocessor, and
the design prevents laser diode oscillation when the
switch (S601) is not CLMP terminal side (wher CLMP
signal is OFF, that is, high level).
Thus, the interlock will no longer function if the switch
(S601) is deliberately set to CLMP terminal side if <CLMP
signal is low level).
In the test mode *, the interlock mechanism will not
function.
Laser diode oscillation will continue, if pin 1 of MS1593FP
( [C101 ) on the preamplifier board loaded on pickup
assembly are connected to GND, or pin 19 is contected to
low level ( ON ), or else the terminals of Q101 aresfnorted
to each other ( fault condition ).

2. EXPLODED VIEWS, PACKING AND PARTS LIST
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 parts. Therefore, when replacing, be sure
to use parts of identical designation.
+ Parts marked by “ @ ” are not always kept in stock. Their delivery time may be longer than usual or they may be unavailable.
