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
IMPORTANT
LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.
LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER: 7 mw
WAVELENGTH: 780 – 785 nm
LABEL CHECK for (PD-F958/MYXQ and PD-F958/MVXQ types)
PD-F958/MYXQ only
Additional Laser Caution
1.Laser Interlock Mechanism
The position of the switch (S651) for detecting loading
state is detected by the system microprocessor, and
the design prevents laser diode oscillation when the
switch (S651) is not on CLMP terminal side (CLMP
REAR
signal is OFF or high level).
Thus, the interlock will no longer function if the switch (S651)
is deliberatery 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 MOTHER 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, close viewing of the
objective lens with the naked eye will cause exposure
to a Class 1 laser beam.

2. CONTRAST OF MISCELLANEOUS PARTS
NOTES : ÷ Parts marked by “ NSP ” are generally unavailable because they are not in our Master Spare Parts List.
÷ The
÷ Reference Nos. indicate the pages and Nos. in the service manual for the base model.
÷ When ordering resistors, first convert resistance values into code form as shown in the following examples.
7 CONTRAST OF PD-F958/KUXQ/CA, MYXQ and MVXQ
PD-F958/ MYXQ, MVXQ and KUXQ/CA are constructed the same except for the following:
Ref.
Mark
No.
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.
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%).
