LABEL CHECK

THIS PIONEER APPARATUS CONTAINS

LASER OF CLASS 1.

SERVICING OPERATION OF THE APPARATUS

S H O U L D B E D O N E B Y A S P E C I A L LY

INSTRUCTED PERSON.

LASER DIODE CHARACTERISTICS

MAXIMUM OUTPUT POWER: 5 mW

WAVELENGTH: 780 – 785 nm

The AEL(accessible emission level) of the laser power output is less then CLASS 1

but the laser component is capable of emitting radiation exceeding the limit for

CLASS 1.

A specially instructed person should servicing operation of the apparatus.

IMPORTANT

WARNING !

Additional Laser Caution

1. Laser Interlock Mechanism

The position of the switch (S1901) for detecting loading

completion is detected by the system microprocessor,

and the design prevents laser diode oscillation when

the switch is not in LPS1 terminal side (when the

mechanism is not clamped and LPS1 signal is

high level.)

Thus, the interlock will no longer function if the switch is

deliberately set to LPS1 terminal side. ( if LPS1 signal

is low level ).

In the test mode∗ the interlock mechanism will not

function. Laser diode oscillation will continue, if pin 41

of TC94A15FG (IC101) on the MAIN Assy is

connected to GND, or else the terminals of Q101 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.
