Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products

5、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

6、 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

7、DIODE CHARACTERISTICS FOR DVD : MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 650 nm FOR CD :MAXIMUM OUTPUT POWER : 7 mW WAVELENGTH : 780 nm Additional Laser Caution * : Refer to page 23. on the service manual RRV2905. LABEL CHECK REAR (DRW2168) 1. Laser Interlock Mechanism The position of the switch (S6

8、51) for detecting loading state is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch (S651) is not on CLMP terminal side (CLMP signal is OFF or high level). Thus, the interlock will no longer function if the switch (S651) is deliberatery set to CL

9、MP terminal side. (low level) The interlock also does not function in the test mode . Laser diode oscillation will continue, if pin 33 of CXA1782CQ (IC151) on the MOTHER BOARD ASSY is connected to GND, or pin 26 of IC351 (LDON) is connected to low level (ON), or else the terminals of Q151 are shorte

10、d 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.
