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.

THIS PIONEER APPARATUS CONTAINS
LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.

LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER: 5 mw
WAVELENGTH: 780 – 785 nm

MYXK type

Additional Laser Caution

1. Laser Interlock Mechanism
The position of the switch (S601) for detecting loading
state is detected by the system microprocessor, and the
design prevents laser diode oscillation when the switch
(S601) is not on CLMP terminal side (CLMP signal is OFF
or high level.). Thus, the interlock will no longer function if
the switch (S601) is deliberately set to CLMP terminal
side (low level).
The interlock also does not function in the test mode∗.
Laser diode oscillation will continue, if pin 33 of
CXA1782CQ (IC151) on the MAIN BOARD ASSY is
connected to GND, or pin 22 of IC301(LDON) is
connected to low level (ON), or else the terminals of Q151
are shorted to each other (fault condition).

2. When the cover is opened with the servo mechanism
block removed and turned over, close viewing of the
objective lens with the naked eye will cause exposure to a

REAR

Class 1 laser beam.

Use nipper or other tool to cut the three sections marked

A

in figure 1. Then remove the spacer

2

While supporting the spindle motor shaft with the
stopper, put spacer on top of the carriage base, and stick
the disc table on top (takes about 9kg pressure). Take
off the spacer.
