1. SAFETY INFORMATION

(Printed on the Rear Panel)

LABEL CHECK

WARNING !

THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1

BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR

CLASS 1.

A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS.

LASER DIODE CHARACTERISTICS

FOR DVD : MAXIMUM OUTPUT POWER : 5 mW

WAVELENGTH : 655 nm

FOR CD : MAXIMUM OUTPUT POWER : 5 mW

WAVELENGTH : 785 nm

This service manual is intended for qualified service technicians; it is not meant for the casual

do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been

trained to properly and safely repair complex products such as those covered by this manual.

Improperly performed repairs can adversely affect the safety and reliability of the product and may

void the warranty. If you are not qualified to perform the repair of this product properly and safely, you

should not risk trying to do so and refer the repair to a qualified service technician.

Additional Laser Caution

1. Loading-status detection switch (S101 on the LOAB assy) are detected

by the microprocessor (IC601 in the DVDM assy).

•To permit the laser diode to oscillate, it is required to set the loading-

status detection switch for the clamp position (the center terminal of S101

is shorted to +3V).

When the voltage of IC101-pin 20 is +3V and IC601 (microprocessor) -

pin 83 is +3V, 650nm laser diode for DVD oscillates in the DVDM Assy.

When the voltage of IC101-pin 20 is +3V and IC601 (microprocessor) -

pin 83 is 0V (GND), 780nm laser diode for CD oscillates in the DVDM

Assy.

In the test mode ∗, the laser diode oscillates when microprocessor detects

a PLAY signal, or when the PLAY key is pressed (S252 ON in the KEYB

assy), with the above requirements satisfied.

2. When the cover is open, close viewing through the objective lens with

the naked eye will cause exposure to the laser beam.
