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
1. Laser Interlock Mechanism
• Loading switch (S101 on the LOAB Assy) is used for interlock
mechanism of the laser.
When this switch turned ON in SW2 (XCLOSE) side (OPEN signal is
0V and XCLOSE signal is 3.5V), a laser becomes the status which can
(Printed on the Rear Panel)

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, 780nm laser diode is always oscillating by half power.
• Laser diode is driving with Q101 (650nm LD) and Q102 (780nm LD)
on the FJMB 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.
The interlock mechanism mentioned above becomes invalid in this
mode.
2. When the cover is open, close viewing through the objective lens with
the naked eye will cause exposure to the laser beam.
