Additional Laser Caution

1. Laser Interlock Mechanism
The position of the switch ($601) for detecting loading
state is detected by the system microprocessor, and the
design prevents laser diode oscillation when the switch
(3601) is not on CLMP terminal side (CLMP signal is OFF
or high level.). Thus, the interlock will no longer function if
the switch (5601) is deliberately set to CLMF' terminal
side (low level).
The interlock also does not function in the test mode*.
Laser diode osctllation will continue. if pin 33 of
CXA1782CQ (IC151) on the MAIN BOARD ASSY is
connected to GND, or pin 22 of |C301(LDON) is
connected to low level (ON), or else the terminals of 0151
are shorted to each other (fault condition).

2. When the cover is opened with the servo mechanism
block removed and turned over, close viewing of the
objective lens with the naked eye will cause exposure to a
Class 1 laser beam.
