Additional Laser Caution

1. Laser interlock Mechanism
The position ol the switch ($651) lor detecting loading
state is detected by the system microprocessor. and the
design prevents laser diode oscillation when the switch
(5651) is not on CLMP terminal side (CLMP signal is OFF
or high level.) Thus. the interlock will no longer lunction it
the switch (8651) is deliberately set to CLMP terminal
side. (low level)
The interlock also does not tunction in the test mode'.
Laser diode oscillation will continue, if pin 1 ol M51593FP
(ICIO1) on the PRE-AMP BOARD ASSY mounted on the
pickup assembly ls connected to GND, or pin 19 is
connected to low level (ON), or else the terminals ol 0101
are shorted to each other (fault condition).

2. When the cover is opened. close viewing at the obiective
lens with the naked eye will cause exposure to a Class 1
laser beam.
