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
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 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.
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 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.
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.
(FOR USA MODEL ONLY)

not be above
0.5mA

Additional Laser Caution
1. Laser Interlock Mechanism
The position of the switch for detecting loading state is
detected by the system microprocessor, and the design
prevents laser diode oscillation when the switch is pressed
physically.
Thus, the interlock will no longer function if the switch is released
physically and deliberatery.
Laser diode oscillation will continue, if pin 46 of TA2065F (IC2)
on the CD SERVO PCB ASSY is connected to GND, or else
the terminals of Q1 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.
LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER: 5 mW
WAVELENGTH: 760 - 800 nm
IMPORTANT
THIS PIONEER APPARATUS CONTAINS
LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.

NOTES:
· 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.
· Screws adjacent to mark on the product are used for disassembly.
