. Laser Interlock
Mechanism
Additional
Laser Caution
The position of the switch (S601) for detecting loading
state
is detected
by the system
microprocessor, and
the design
prevents
laser diode
oscillation
when
the
switch (S601) is not on CLMP
terminal side (CLMP
signal is OFF or high level).
Thus, the interlock will no longer function if the switch
(S601)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
(IC101) 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 Q101
are shorted
to each
other (fault
condition).
CAUTION
