Additional Laser Caution
1.
• Laser diode is driving with Q2309, Q2310 (650 nm LD) and Q2308,
Q2311 (780 nm LD) on the MAIN 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.
