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
causecancer, birth defects or other reproductive harm.
Health & Safety Code Section 25249.6 ­ Proposition 65
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 par ts 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
ser vice technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known earth ground (waterpipe
, 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.

WARNING !
THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN
CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING
THE LIMIT FOR CLASS 1.
A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE
APPARATUS.
LASER DIODE CHARACTERISTICS
FOR DVD : MAXIMUM OUTPUT POWER : 5 mW
WAVELENGTH : 650 nm
FOR CD :
MAXIMUM OUTPUT POWER : 7 mW
WAVELENGTH : 780 nm
LABEL CHECK
(Printed on the Rear Panel)
Additional Laser Caution
: See page 87.
1. Loading-status detection switch (S101 on the LOAB assy) are detected
by the microprocessor (IC601 in the DVDM assy).
· To permit the laser diode to oscillate, it is required to set the loading-
status detection switch for the clamp position (the center terminal of
S101 is shorted to +3V).
When the voltage of IC101-pin 21 is +3V, IC601 (microprocessor)
-pin 83 is +3V and IC601-pin 84 is +3V, 650nm laser diode for DVD
oscillates in the DVDM Assy.
When the voltage of IC101-pin 21 is +3V, IC601 (microprocessor)
-pin 83 is 0V (GND) and IC601-pin 84 is +3V, 780nm laser diode for
CD oscillates in the DVDM Assy.
In the test mode * , the laser diode oscillates when microprocessor
detects a PLAY signal, or when the PLAY key is pressed (S9043 ON in
the KEYB assy), with the above requirements satisfied.
2. When the cover is open, close viewing through the objective lens with
the naked eye will cause exposure to the laser beam.

· Perform only "How to reset Power-on time B" in "7.1.7."
When the DVDM Assy is to be replaced
Replace the Assy, following the procedures described in "7.6 DISASSEMBLY."
· Before disconnecting the FFC cable between the Pickup Assy and the DVDM Assy (CN111), be sure to short-circuit the
short-circuiting land of the pickup with Sn-Ag-Cu alloy.
· If the AJKB Assy is to be replaced at the same time, resetting of the ID number and copying of ID data are required.
· See "7. GENERAL INFORMATION."
When the AJKB Assy is to be replaced
· Copying of ID data is required. Also, destination setting and input of the serial number are required.
· See "7. GENERAL INFORMATION."
· If the DVDM Assy is to be replaced at the same time, besides the settings mentioned above, resetting of the ID number is
also required.
· See "7. GENERAL INFORMATION."
When downloading the firmware
