LABEL CHECK

CLASS 1
LASER PRODUCT

IMPORTANT
THIS PIONEER APPARATUS CONTAINS
LASER OF CLASS 1.
SERVICING OPEFIATlON OF THE APPARATUS
SHOULD BE DONE BV A SPEClALLY
INSTRUCTED PERSON.

LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER: 5 mW
WAVELENGTH: 760 . 800 nm

Additional Laser Caution

. Laser Interlock Mechanism

The loading position detect switch (in CD mechanism
assembly) is set to "CLMP ON(CD CLOSE)" (ON:Iow
|eve|,OFF:high level) position, the system control
|C(|C7002) get the "CLMP" signal, and hand the laser
"LDON" signal to |C1101.

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 9 of TA2150FN
(IC1 101) on the RF AMP is connected to GND, or pin 10 is
connected to low level (ON), or else the terminals of
01101 are shorted to each other (fault condition).

. When the cover is opened, close viewing of the objective

lens with the naked eye will cause exposure to a Class 1
laser beam.
