SAFETY INFORMATION
Additional Laser Caution
1.
• Laser diode is driving with Q2304 (650 nm LD) and Q2303
(780 nm LD) on the MAI
N
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 Service mode
∗
, there is the mode that the laser
oscillates except for the disc judgment and playback.
LD
O
N
mode in the test mode oscillates with the laser forcibly.
2.
