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,theinterlockwillnolongerfunctioniftheswitch(S9501)

is released physically and deliberatery.

The interlock also does not function in the test mode

∗

Laser diode oscillation will continue, if pin 1 of

CXA1821M (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 coverisopened, close viewingof the objective

lens with the naked eye will cause exposure to a Class

1 laser beam.

LABEL CHECK (For MYXJ and NVXJ Types)

LASER DIODE CHARACTERISTICS
