Additional Laser Caution

1.Laser Interlock Mechanism

The position of the switch for detecting loading state is

detected by the system microprocessor, and the design

prevents laser diode oscillation when the switch is pressed

physically.

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

physically and deliberatery.

Laser diode oscillation will continue, if pin 46 ofTA2065F (IC2)

on the CD SERVO PCB ASSY is connected to GND, or else

the terminals of Q1 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.

LASER DIODE CHARACTERISTICS

MAXIMUM OUTPUT POWER: 5 mW

WAVELENGTH: 760 - 800 nm

IMPORTANT

THIS PIONEER APPARATUS CONTAINS

LASER OF CLASS 1.

SERVICING OPERATION OF THE APPARATUS

SHOULD BE DONE BY A SPECIALLY

INSTRUCTED PERSON.
