Additional Laser Caution

1. Laser nterlock Mechanism
The position of the switch (8601) for detecting loading
state is detected by the system microprocessor, and the
design prevents laser diode oscillation when the switch
I$601) is not on CLMP terminal side (CLMP signal is OFF
or high level.) Thus. the interlock will no longer function i
the switch (5601) is deliberately set to CLI'VIP terminal
side. (low level)
The interlock also does not function in the test mode*.
Laser diode oscillation will cortinue, if pin 1 of M51 593FP
lIC101) on the PRE-AMP BOARD ASSY mounted on the
pickup assembly is connected to GND, or pin 19 is
connected to low level ION), or else the terminals of 0101
are shorted to each other (fault condition).
