THIS PIONEER APPARATUS CONTAINS
IMPORTANT
LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.
DBDXJ and YPWXJ TYPES
LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER: 5 mW
WAVELENGTH: 780 - 785 nm

DDXJ/AR TYPE
Additional Laser Caution
1.Laser Interlock Mechanism
The position of the switch (S9501) for detecting loading
state is detected by the system microprocessor, and
the design prevents laser diode oscillation when the
switch (S9501) is pressed physically.
Thus, the interlock will no longer function if the switch (S9501)
is released physically and deliberatery .
The interlock also does not function in the test mode ∗.
Laser diode oscillation will continue, if pin 1 of
CXA1821M (IC8101) on the CD ASSY 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 e xposure to a Class
1 laser beam.

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.
Screws adjacent to mark on product are used for disassembly.
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%).
