1. SAFETY INFORMATION

This service manual is intended for qualified service technicians ; it is not meant for the casual do-it­yourselfer. 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.

(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 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.

Reading should
not be above

0.5mA

Earth
ground

Device
under
test

Also test with
plug reversed
(Using AC adapter
plug as required)

Leakage
current
tester

Test all
exposed metal
surfaces

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
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.

AC Leakage Test

2

DV-K303C

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 : 655 nm

FOR CD : MAXIMUM OUTPUT POWER : 5 mW

WAVELENGTH : 785 nm

WARNING !

Additional Laser Caution

1. Inside detection switch (S201 on the SMEB assy) and loading­status detection switch (S9503 on the MOT OR assy) are detected
by the microprocessor (IC11 in the DVDM assy).

• To permit the laser diode to oscillate, it is required to set the
inside detection switch for the inside position (S201 : ON) and to
set the loading-status detection switch for the clamp position (the
center terminal of S9503 is shorted to +5V). The 655 nm laser
diode for DVD oscillation will continue if pin 19 of IC1 is shorted
to +5V (fault condition) in the DVDM assy.
The 785 nm laser diode for CD oscillates if pin 20 of IC1 is shorted
to +5V 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
(S131 ON in the FLKY 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.

∗ : See page 47.
