Additional Laser Caution
1. Laser Interlock Mechanism
The position of the switch (S9501) for detecting loading
state is detected by the system microprocessor, and
the design prevents laser diode oscillation when the
switch (S9501) is pressed physically.
Thus, the interlock will no longer function if the switch (S9501)
is released physically and deliberatery.
The interlock also does not function in the test mode
.
Laser diode oscillation will continue, if pin 62 of
LA9240ML (IC1101) on the $M SERVO VCD Assy
mounted on the $M MECHANISM VCD is connected to
GND, or else the terminals of Q1101 are shorted to each
other (fault condition).
2. When the cover is opened, close viewing of the objective
lens with the naked eye will cause exposure to a Class
1 laser beam.
: Refer to page 73.
LABEL CHECK (For DLXJ/NC Type)
LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER: 5 mW
WAVELENGTH: 780 nm to 785 nm
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.
