Laser Interlock MechanismThe position of the switch (S9002) for detecting loadingcompletion is detected by the system microprocessor, and thedesign prevents laser diode oscillation when the switch is not inLPS1 terminal side (when the mechanism is not clamped andLPS1 signal is high level.)Thus, the interlock will no longer function if the switch isdeliberately 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 (pin 3) ofAN22022A (IC7002) on the SRVA Assy is connected to GND,or else the terminals of Q7002 (Q7001) are shorted to eachother (fault condition).2. When the cover is opened, close viewing of the objective lenswith the naked eye will cause exposure to a Class 1 laser beam.For DVD Wave length (typ) : 655 nmOperation output : 3 mW CW, Class 1Maximum output : Class 1 (Under fault condition)For CD Wave length (typ) : 790 nmOperation output : 4.5 mW CW, Class 1Maximum output : Class 1 (Under fault condition)Laser Pickup specifications and Laser characteristics
