1. SAFETY INFORMATION
This service manual is intended for qualified service technicians ; it is not meant for the casual do-ityourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual. Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty. If you are not qualified to perform the repair of this product properly and safely, you should not risk trying to do so and refer the repair to a qualified service technician.

WARNING ! THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR CLASS 1. A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS.

LASER DIODE CHARACTERISTICS MAXIMUM OUTPUT POWER: 5 mW WAVELENGTH: 780 nm to 785 nm

LABEL CHECK (For DLXJ/NC Type)
Printed on the Rear Panel

DLXJ/NC Type

Additional Laser Caution
1. Laser Interlock Mechanism The position of the switch (S9501) for detecting loading state is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch (S9501) is pressed physically. Thus, the interlock will no longer function if the switch (S9501) is released physically and deliberatery. The interlock also does not function in the test mode �. Laser diode oscillation will continue, if pin 62 of LA9240ML (IC1101) on the $M SERVO VCD Assy mounted on the $M MECHANISM VCD is connected to GND, or else the terminals of Q1101 are shorted to each other (fault condition). 2. When the cover is opened, close viewing of the objective lens with the naked eye will cause exposure to a Class 1 laser beam.
