THIS PIONEER APPARATUS CONTAINS

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
LABEL CHECK
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.
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
deliberatery 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.
Additional Laser Caution
Refer to page 22.
