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.

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

FOR DVD : MAXIMUM OUTPUT POWER : 7 mW

WAVELENGTH : 650 nm

FOR CD :

MAXIMUM OUTPUT POWER : 5mW

WAVELENGTH : 780 – 785 nm

(Printed on the Rear Panel)

Health & Safety Code Section 25249.6 – Proposition 65

Additional Laser Caution

1. Inside detection switch (S201 on the SMEB assy) and loading-

status detection switch (S301 on the LOSB assy) are detected

by the microprocessor (IC501 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 S301 is shorted to +5V). The 650 nm laser

diode for DVD oscillation will continue if pin 19 of IC101 is shorted

to +5V (fault condition) in the DVDM assy.

The 780 nm laser diode for CD oscillates if pin 20 of IC101 is

shorted to +5V in the DVDM assy.

In the test mode ∗ , the laser diode oscillates when microproces-

sor detects a PLAY signal, or when the PLAY key is pressed

(S113 ON in the FLKY assy), with the above requirements satis-

fied.

2. When the cover is open, close viewing through the objective lens

with the naked eye will cause exposure to the laser beam.
