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.
LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER : 7 mW
WAVELENGTH : 780 to 785 nm
IMPORTANT
THIS PIONEER APPARATUS CONTAINS
LASER
OF
CLASS
1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.
Additional Laser Caution
1. Laser Interlock Mechanism
The ON/OFF (ON : low level, OFF : high level)
status of S601 (LPS1) and S602 (LPS2)
switches for detecting the loading state is
detected by the system microprocessor, and
the design prevents laser diode oscillation
except when both switches S601 and S602
are ON (low level or clamped state).
Thus, interlock will no longer function if
switches S601 (LPS1) and S602 (LPS2) are
deliberately shorted (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 MOTHER
BOARD ASSY is connected to GND, or pin
50 of IC351 (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 to be turned over,
close viewing of the objective lens with the
naked eye will cause exposure to a Class 1
laser beam.

For the applying amount of lubricants or glue, follow the instructions in this manual.
(In the case of no amount instructions, apply as you think it appropriate.)
Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.
The
mark found on some component parts indicates the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of identical designation.
Screws adjacent to
mark on product are used for disassembly.
Reference Nos. indicate the pages and Nos. in the service manual for the base model.
NOTES:
·When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).
