Laser Interlock MechanismThe position of the switch (S601) for detecting loadingstate is detected by the system microprocessor, and thedesign prevents laser diode oscillation when the switch(S601)

27、is not on CLMP terminal side (CLMP signal is OFFor high level.). Thus, the interlock will no longer function ifthe 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(IC
