Addlnonal Laser Caunon
1. Laser Interlock Mechanism

The position of the switch ($601) for detecting loading
state is detected by the system microprocessor, and the
design prevents laser diode oscillation when the switch
(8601) in not CLMP terminal side (when CLMP signal is
R OFF or high level).

Thus, the interlock will no longer function it the switch

(8601) is deliberately set to CLMP terminal side (low
level).

The interlock also dose not function in the test mode *.
Laser diode oscillation will continue. if pin 1 of M51593FP
([0101) 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 C1101
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
