Additional Laser Caution

1. Laser Interlock Mechanism
The position of the switch (S501) on the LOADING A Assy
for detecting loading state is detected by the system
microprocessor, and the design prevents laser diode
oscillation when the switch (S501) is not on TRAY terminal
side (TRAY signal is OFF or high level.). Thus, the
interlock will no longer function if the switch (S501) is
deliberately set to TRAY terminal side (low level).
The interlock also does not function in the test mode
Laser diode oscillation will continue, if pin 32 of CN101 on
the CD-R CORE ASSY is connected to low level.
2. When the cover is opened with the servo mechanism
block removed and turned over, close viewing of the
objective lens with the naked eye will cause exposure to a
Class 1 laser beam.

Additional Laser Caution
1. Laser Interlock Mechanism
The position of the switch (S101) on the SERVO
MECHANISM Assy for detecting loading state is detected
by the system microprocessor, and the design prevents
laser diode oscillation when the switch (S101) is not on
CLMP terminal side (CLMP signal is OFF or high level.).
Thus, the interlock will no longer function if the switch
(S101) is deliberately set to CLMP terminal side (low
level).
The interlock also does not function in the test mode
Laser diode oscillation will continue, if pin 1 of CXA2570
(IC1101) on the MAIN ASSY is connected to GND, or pin
12 is connected to low level (ON), or else the terminals of
Q1101 are shorted to each other (fault condition).
2. When the cover is opened with the servo mechanism
block removed and turned over, close viewing of the
objective lens with the naked eye will cause exposure to a
Class 1 laser beam.
