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.
LABEL CHECK
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 (S8501) for detecting loading
state is detected by the system microprocessor, and
the design prevents laser diode oscillation when the
switch (S8501) is pressed physically.
Thus,theinterlockwillnolongerfunctioniftheswitch(S8501)
is released physically and deliberatery.
The interlock also does not function in the test mode ∗ .
Laser diode oscillation will continue, if pin 62 of
LA9240ML (IC8101) on the CDASSY mounted on the
$M Loading Mechanism assembly is connected to GND,
or else the terminals of Q8101 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 Class 1 laser beam.
∗ : Refer to page 52 on the service manual RRV1883.

2. CONTRAST OF MISCELLANEOUS PARTS
CONTRAST TABLE
XR-A100/MYXK, NVXK, YPWXJ, XR-A100-K/MYXK, NVXK and XR-A100-K/KCXJ are constructed the same
except for the following :
NOTES: •Parts marked by "NSP" and ⊗can not be supplied.
•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.
•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%).

Adjust VR1001 in the POWER Assy so that the voltage of Vp checking point W104 is 17.5 ± 0.1V.
Adjustment can be made when no load is applied while the power is turned ON and no signal is sent, as well as for the GND voltage or
for the chassis.
Adjustment is required when the 5volte regurator, IC1001 (NJM78M05FA) in the POWER Assy are replaced.
