LABEL CHECK (For DLXJ/NC types)

Additional Laser Caution

1. Laser Interlock Mechanism

The position of the switch (S8501) for detecting loading

state is detected by the system microprocessor, and

the design prevents laser diode oscillation when the

switch (S8501) is pressed physically.

Thus, the interlock will no longer function if the switch (S8501)

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 (IC8101) on the CD ASSY mounted on the

$M Loading Mechanism assembly is connected to GND,

or else the terminals of Q8101 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 60.
