IMPORTANT

THIS PIONEER APPARATUS CONTAINS

LASER OF CLASS 1.

SERVICING OPERATION OF THE APPARATUS

SHOULD BE DONE BY A SPECIALLY

INSTRCUTED PERSON.

LASER DIODE CHARACTERISTICS

MAXIMUM OUTPUT POWER: 5 mw

WAVELENGTH: 708-785 nm

ZYXJ type Only ZYXJ type Only

ZVXJ type Only

(Right side view)

LABEL CHECK

1. Laser Interlock Mechanism

The loading position detect switch (in CD mechanism

assembly) is set to "CLMP ON(CD CLOSE)" (ON:low

level,OFF:high level) position, the system control

IC(IC5501) get the "CLMP" signal, and hand the laser

"LDON" signal to IC1101.

Then a laser diode can be lighted except when the level of

signal CLMP is low.

The interlock also does not function in the test mode∗.

Laser diode oscillation will continue, if pin 1 of CXA1821M

(IC1101) on the CDMAIN UNIT is connected to GND, or

pin 19 is connected to low level (ON), 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 54.
