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. SAFETY INFORMATION
LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER: 7 mw
WAVELENGTH: 780 – 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 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
signal is OFF or high level).
Thus,theinterlock will nolongerfunction if theswitch(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 BOARDASSY
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.
* : Refer to page 29. on the service manual RRV2085.

2. CONTRAST OF MISCELLANEOUS PARTS
NOTES : ÷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.
÷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.
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%).
560 Ω=56 ×101 =561................................................... RD1/4PU 561J
47k Ω=47 ×10 3=473 .................................................. RD1/4PU 473J
0.5 Ω=R50 ...................................................................... RN2H Â50K
1 Ω=1R0 ......................................................................... RS1P 1Â0K
Ex. 2 When there are 3 effective digits (such as in high precision metal film resistors).
5.62k Ω=562 ×10 1=5621 ........................................... RN1/4PC 5621F
