Additional Laser Caution
1. Laser Interlock Mechanism
The position of the switch (S8501) for detecting loading
state is detected by the system microprocessor, and
the design prevents laser diode oscillation when the
switch (S8501) is pressed physically.
Thus, the interlock will no longer function if the switch (S8501)
is released physically and deliberatery.
The interlock also does not function in the test mode
.
Laser diode oscillation will continue, if pin 62 of
LA9240ML (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 exposure to a Class
1 laser beam.
: Refer to page 60.
