Additional Laser Caution

1 Laser Interlock Mechanism
The position of the switch ($8501) fordetecting loading
state is detected by the system microprocessor, and
the design prevents laser diode oscillation when the
switch (88501) is pressed physically.
Thus,theinterlod is released physically and deliberater
The interlock also does not function in the test mode *.
Laser diode oscillation Will continue, if pin 62 of
LA9240ML (l08101) on the CD ASSY mounted on the
$M Loading Mechanism assembly is connected to GND,
orelse the terminals of 08101 are shorted to each other
(fault condition).

2tWhen the cover is opened, close viewing of the
objective lens with the naked eye will cause exposure
to a Class 1 laser beam.
