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

8、CHARACTERISTICS FOR DVD : MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 650 nm FOR CD :MAXIMUM OUTPUT POWER : 7 mW WAVELENGTH : 780 nm Additional Laser Caution : See page 107 1. Laser Interlock Mechanism Loading switch (S101 on the LOAB Assy) is used for interlock mechanism of the laser. When this switch

9、 turned ON in SW2 (XCLOSE) side (OPEN signal is 0V and XCLOSE signal is 3.5V), a laser becomes the status which can completely oscillation. Furthermore, the laser completely oscillates in the disc judgment and disc playback. When player is power ON state and laser diode is not completely oscillating

10、, 780nm laser diode is always oscillating by half power. Laser diode is driving with Q101 (650nm LD) and Q102 (780nm LD) on the DVDM Assy. Therefore, when short-circuit between the emitter and collector of these transistors or the base voltage is supplied for transistors turn on, the laser oscillate

11、s. (failure mode) In the test mode , there is the mode that the laser oscillates except for the disc judgment and playback. LD ON mode in the test mode oscillates with the laser forcibly. The interlock mechanism mentioned above becomes invalid in this mode. 2. When the cover is open, close viewing t

12、hrough the objective lens with the naked eye will cause exposure to the laser beam. LABEL CHECK XV-EV61/DLXJ/NC (Printed on the Rear Panel B) SOUND MODE ADVANCED SURROUND SURROUND STANDBY/ON ST.
