Additional Laser Caution

l. Laserlnterlock Mechanism
The position of the switch (8601) for detecting loading
completion is detected by the system microprocessor. and
the daign prevents laser diode oscillation when the
switch ($601) is not @175 terminal side (when CLMP
signal is OFF. that is. high level).
Thus, the interlock will no longer function it the switch
($601) is deliberately set to CLMP terminal side (if CLMP
signal is low level),
In the test mode 1:. the interlock mechanism will not
lunction.
Laser diode oscillation will continue, it pin l of M51593FP
( ICIOI ) on the preamplifier board loaded on pickup
assembly are connected to GND, or pin 19 is connected to
low level I 0N ). or else the terminals of 0101 are shorted
to each other (Iault condition )I
