1. SAFETY INFORMATIONThis 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 Cod e Section 25249.6
Proposition 65
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 MODLE
CANADIEN SEULEMENT) Les symboles de fusible (fusible de type
rapide) et/ou (fusible de type lent) sur CCI indiquent que les
pices de remplacement doivent avoir la mme dsignation.
(FOR USA MODEL ONLY) 1. SAFETY PRECAUTIONSThe following check
should be performed for the continued protection of the customer
and service technician.
LEAKAGE CURRENT CHECKMeasure 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 0.5 mA.
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 NOTICEMany 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 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
additional copies of, PIONEER Service Manual may be obtained at a
nominal charge from PIONEER.

IMPORTANT THIS PIONEER APPARATUS CONTAINS LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.
LASER DIODE CHARACTERISTICS MAXIMUM OUTPUT POWER: 5 mw
WAVELENGTH: 780 785 nm
LABEL CHECK (for WY type)
Additional Laser Caution1. Laser Interlock Mechanism The
position of the switch (S1) for detecting loading completion is
detected by the system microprocessor, and the design prevents
laser diode oscillation when the switch is not in LPS1 terminal
side (when the mechanism is not clamped and LPS1 signal is high
level.) Thus, the interlock will no longer function if the switch
is deliberatery set to LPS1 terminal side. ( if LPS1 signal is low
level ). In the test mode the interlock mechanism will not
function. Laser diode oscillation will continue, if pin 33 of
CXA1782CQ (IC101) on the MOTHER BOARD ASSY is connected to GND, or
pin 43 of IC701 (LDON) is connected to low level (ON), or else the
terminals of Q101 are shorted to each other (fault condition). 2.
When the cover is opened, close viewing of the objective lens with
the naked eye will cause exposure to a Class 1 laser beam.

2. EXPLODED VIEWS AND PARTS LISTNOTES : Parts marked by NSP are
generally unavailable because they are not in our Master Spare
Parts List. The 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. Screw
adjacent to mark on the product are used for disassembly.

5. PCB PARTS LISTNOTES : Parts marked by NSP are generally
unavailable because they are not in our Master Spare Parts List.
mark found on some component parts indicates the importance of the
safety factor of the part. The Therefore, when replacing, be sure
to use parts of identical designation. 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%). 560 = 56 10 1 = 561
................................................... RD1/4PU 5 6 1 J
47k = 47 10 3 = 473
.................................................. RD1/4PU 4 7 3 J
0.5 = R50
......................................................................
RN2H 5 0 K 1 = 1R0
.........................................................................
RS1P 1 0 K Ex. 2 When there are 3 effective digits (such as in high
precision metal film resistors). 5.62k = 562 10 1 = 5621

6.2 ADJUSTMENT6.2.1 How to Start/Cancel Test Mode[ Precautions
for Test Mode ](1) If a soiled or damaged disc is played back and a
GFS error is generated, the system may not perform a STOP operation
and may run out of control, although muting ON/OFF will be
performed. If the system does run out of control, press the CUE key
to switch the power OFF. (2) Do NOT press any key while an
OPEN/CLAMP, SPINDLE KICK, or FOCUS SEARCH operation is in progress.
Be sure to wait until the operation is completed before calling the
next operation.

the AC outlet whenever removing the card flexible cable from the
connector for maintenance, etc. Hold the both sides of the card
flexible cable with both hands to disconnect the cable straight.
(Even if the power has been switched OFF, previously charged
voltage may remain in the capacitor, etc. If the electrodes of the
card flexible cable and those of the connector come in contact by
accident, a malfunction may occur.)

MASTER TEMPO button The master tempo function is turned ON/OFF. If
the button is held depressed for 2 seconds or more, the tempo
adjust dial's variable range is changed (10% or +10% to 16%). When
the variable range is changed, the newly selected numerical range
is displayed for about 2 seconds (10.0 / 16.0). The variable range
is set by default to the 10 setting whenever power is first turned
on.
= TIME MODE/AUTO CUE buttonTwo functions are available. [Time
display] Each time this button is pressed, the time display changes
between the elapsed playback time of the track and the remaining
playback time of the track (REMAIN). The REMAIN display appears
when power is turned ON. [Auto Cue function] When a disc is
initially loaded or when performing track search, this function
automatically sets the cue point (the point immediately preceding
actual sound output). The Auto Cue function defaults to OFF when
power is first turned on.
1 POWER switch(Located on rear panel) Provides electrical power
to the player.
~ TEMPO control knobThe playback tempo can be changed with this
knob. The center clicked position is for normal playback tempo. If
you slide the knob (down) towards you (+ side), the music tempo
quickens. If the knob is away from you ( side), the music tempo
slows.
