Additional Laser Caution 1. Laser Interlock Mechanism The

6、 position of the switch (S8902) for detecting loading completion is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch is not in LPS1 terminal side (when the mechanism is not clamped and LPS1 signal is high level.) Thus, the interlock will no longe

7、r function if the switch is deliberately set to LPS1 terminal side. ( if LPS1 signal is low level ). In the test mode the interlock mechanism will not function. Laser diode oscillation will continue, if pin 5 of AN22022A (IC7004) on the SRV Assy is connected to GND, or else the terminals of Q7002 ar
