Additional Laser Caution
=
. Laser Interlock Mechanism
The ON/OFF (ON: low level, OFF: high level)
status of S601 (LPS1) and S602 (LPS2)
switches for detecting the loading state is
detected by the system microprocessor, and
the design prevents laser diode oscillation
except when both switches S601 and S602
are ON (low level or clamped state).
Thus, interlock will no longer function if
switches S601 (LPS1) and S602 (LPS2) are
deliberatery shorted (low level). The interlock
also does not function in the test mode.
Laser diode oscillation will continue, if pin 33
of CXA1782CQ (IC151) on the MOTHER
BOARD ASSY is connected to GND, or pin
50 of IC351 (LDON) is connected to low level
(ON), or else the terminals of Q151 are shorted
to each other (fault condition).

RADIATION WHEN OPEN,
AVOID EXPOSURE
TO BEAM PRW1018
2. When the cover is opened with the servo
mechanism block removed to be turned over,
close viewing of the objective lens with the
naked eye will cause exposure to a Class 1
laser beam.
