1. S AF ET Y INFORMATION
This service manual is intended for qualified service technici an s; 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 cove re d by this manual.
Improperly performed repairs can adversely affect the safety and re li ability 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
Lead in solder used in this product is listed by the California Health and Welfare agency as a known reproductive toxicant which
may cause birth defects or other reproductive harm (California Health & Safety Code, Section 25249.5).
When servicing or handling circuit boards and other components which contain lead in solder, avoid unprotected skin contact wi th
the solder. Also, when soldering do not inhale any smoke or fumes produced.

IMPORTANT
THIS PIONEER APPARATUS CONTAINS
LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUTED PERSON .
.--- LASER DIODE CHARACTERISTICS -
MAXIMUM OUTPUT POWER : 5 mw
WAVELENGTH: 780 - 785 nm
~---- Additional Laser Caution ------~
1. Laser Interlock Mechanism
The position of the switch (S902) for detecting loading
completion is detected by the system microprocessor,
and the design prevents laser diode oscillation when the
switch (S902) is not in CLMP terminal side (when the
mechanism is not clamped and CLMP signal is high
level.) Thus, the interlock will no longer function if the
switch (S902) is deliberately set to CLMP terminal side. (if
CLMP signal is l ow level).
In the test mode * the interlock mechanism will not
function.
Laser diode oscillation will continue, if pin 4 of TA2066F
(IC204) on the MOTHER board assy connected to GND,
or pin 19 is connected to high level (ON), or else the
terminals of 0206 are shorted to each other (fault
condition).
2. When the cover is opened, close viewing of the objective
lens with the naked eye will cause exposure to a ~ass 1
laser beam .
*Refer to page 18.
