NV Type

The position oi the switch ($601) lor detecting loading
state is detected by the system microprocessor, and the
design prevents laser diode oscillation when the switch
($601) is not on CLMP terminal side (CLMP signal is OFF
or high level.). Thus. the interlock will no longer lunctlon ii
the switch ($601) is deliberately set to CLMP lenninal side
(low level).

The interlock also does not lunction in the test mode'.
Laser diode oscillation will continue, it pin t of M51593FP
(ICIOI) on the PRE-AMP BOARD ASSV mountdd 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 condition).

. When the cover is opened, close viewing at the objective

lens with the naked eye will cause exposure to a Class 1
laser beam.
