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.
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 : 5 mW
WAVELENGTH : 655 nm
FOR CD : MAXIMUM OUTPUT POWER : 5mW
WAVELENGTH : 785 nm
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 (IC11 in the DVDM assy).
• T o 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 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 (S106 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 42.
