IMPORTANT
THIS PIONEER APPARATUS CONTAINS
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 : 650 nm
Additional Laser Caution
1. Inside detection switch (S201 on the INSB 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 laser diode
oscillation will continue if pin 13 of IC101 is shorted to +5V (fault
condition) 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
(S106 ON in the FLKY 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.
∗: Refer to the service guide RRV2004.
(Printed on the Rear Panel)
