IMPORTANT
THIS PIONEER APPARATUS CONTAINS
LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.
LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER: 5 mw
WAVELENGTH: 780-785 nm
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.
