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
FOR DVD : MAXIMUM OUTPUT POWER : 5 mW
WAVELENGTH : 650 nm
FOR CD :
MAXIMUM OUTPUT POWER : 5 mW
WAVELENGTH : 780 nm
Additional Laser Caution
: See page 51.
1.
· Laser diode is driving with Q2303,Q2305(650nm LD) and Q2302,
Q2304(780nm LD)on the DVD MT PCB 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 oscillates. (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.
2. When the cover is open, close viewing through the objective lens with
the naked eye will cause exposure to the laser beam.
