1. Laser Interlock Mechanism
The position of the switch (88501) for detecting loading
state is detected by the system microprocessor, and
the design prevents laser diode oscillation when the
( switch (88501) is pressed physically.
Thus, the interlock will no longerfunction if the switch (88501)
is released physically and deliberatery.
The interlock also does not function in the test mode *.
