1. SAFETY INFORMATION

LABEL CHECK (for YPWXJ type)

Printed on the Rear Panel

CLASS I
LASER PRODUCT

CAUTION
INVISIBLE LASER
RADIATION WHEN OPEN,
AVOID EXPOSURE
TO BEAM PRW1018

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 7
MAXIMUM OUTPUT POWER: 5 mW
WAVELENGTH: 780 . 785 nm

Additional Laser Caution

. Laser Interlock Mechanism

The position of the switch ($9501) for detecting loading
state is detected by the system microprocessor, and
the deSIgn prevents laser diode oscillation when the
switch (89501) is pressed physically.

Thus, the interlock will no longer function if the switch (89501)
is released physically and deliberatery.

The interlock also does not function in the test mode *.
Laser diode oscillation will continue, if pin 1 of
CXA1821 M (ICS101) on the CD ASSY mounted on the
SM Loading Mechanism assembly is connected to GND,
or else the terminals of 08101 are shorted to each other
(fault condition).

. When the cover is opened, close viewing of the objective

lens with the naked eye will cause exposure to a Class
1 laser beam.
