17、OAB Assy fordetecting loading state is detected by the systemmicroprocessor, and the design prevents laser diodeoscillation when the switch (S101) is not on TRAY terminalside (TRAY signal is OFF or high level.). Thus, theinterlock will no longer function if the switch (S101) isdeliberately set to TR

18、AY terminal side (low level).The interlock also does not function in the test mode .Laser diode oscillation will continue, if pin 1 of CN101 onthe CD-R CORE ASSY is connected to low level.2.
