2.1 PACKING
2. EXPLODED VIEWS AND PARTS LIST
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.
•
Screws adjacent to mark on the product are used for disassembly.
IMPORTANT
THIS PIONNER APPARATUS CONTAINS
LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.
LASER DIODE CHARACTERISTICS
FOR DVD : MAXIMUM OUTPUT POWER : 7 mw
WAVELENGTH : 650 nm
FOR CD :
MAXIMUM OUTPUT POWER : 5mW
WAVELENGTH : 780 – 785 nm
Additional Laser Caution
1. Inside detection switch (S201 on the SMEB assy) and loading-
status detection switch (S301 on the LOSB assy) are detected
by the microprocessor (IC501 in the DVDM assy).
• To permit the laser diode to oscillate, it is required to set the
inside detection switch for the inside position (S201 : ON) and to
set the loading-status detection switch for the clamp position (the
center terminal of S301 is shorted to +5V). The 650 nm laser
diode for DVD oscillation will continue if pin 19 of IC101 is shorted
to +5V (fault condition) in the DVDM assy.
The 780 nm laser diode for CD oscillates if pin 20 of IC101 is
shorted to +5V in the DVDM assy.
In the test mode
∗
, the laser diode oscillates when microproces-
sor detects a PLAY signal, or when the PLAY key is pressed
(S113 ON in the FLKB assy), with the above requirements satis-
fied.
2. When the cover is open, close viewing through the objective lens
with the naked eye will cause exposure to the laser beam.
