1. Laser Interlock Mechanism

Additional Laser Caution

The position of the switch [ Leaf switch lVSKlOl lion the
LOADING BOARD ASSV ) for detecting loading state is
detected by the system microprocessor, and the design
prevents laser diode oscillation when the switch is not on
CLMP terminal side {CLMP signal is OFF or high level).
Thus, the interlock will no longer function if the switch is
deliberately set to CLMP terminal side. (low level)

The interlock also does not function in the test mode.
Laser diode oscillation will continue, if pin 1 of M51593FP
(IC10l) on the PRE-AMP BOARD ASSY mounted on the
pickup assembly is connected to GND, or pin 19 is
connected to low level (ON), or else the terminals of 0101
are shorted to each other (fault conditionlt

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,
